Strengthening the SOLid-state research capacities in Zagreb by the introduction of the Nuclear Magnetic Resonance method

Final Report Summary - SOLENEMAR (Strengthening the solid-state research capacities in Zagreb by the introduction of the nuclear magnetic resonance method)

Executive summary:

Given that Nuclear magnetic resonance (NMR) is today an unavoidable method in solid state physics, the main goal of the project is the implementation of ssNMR method (ssNMR) at PDFS that would serve for the microscopic investigations of strongly correlated electron systems, high temperature superconductors, quantum magnets, conducting polymers, carbon nanotubes, and many other problems of condensed matter physics.

The Physics Department of the Faculty of Science at the University of Zagreb (PDFS) is the leading university physics department in Croatia with 70 internationally recognised scientists and 660 undergraduate and graduate students. A considerable part of the research in the Department of Physics, Faculty of Science, University of Zagreb, is devoted to solid state physics and material science. Current investigations are oriented towards new materials with unusual electric and magnetic properties. Several experimental methods are used to analyse the materials properties (X-Ray, diffraction, electron microscopy, transport, calorimetric, magnetic and microwave measurements). Implementation of ssNMR method will complement the research infrastructure of PDFS for investigation of new materials. The final goal of the project is an internationally recognised ssNMR group with a large potential to participate in national and international research projects, in particular Seventh Framework Programme (FP7).

To achieve this goal, specific objectives are:

1. Acquisition of ssNMR equipment to increase the infrastructure for materials research in Zagreb. The ssNMR spectrometer should be suitable for measurements of broad spectral lines, at low temperatures, and in variable magnetic fields.
2. Increase of human potential for ssNMR research at Department of Physics.
3. Strengthen the cooperation with European NMR centres of excellence by exchange of experience.
4. Organisation of workshops and seminars with a goal of spreading the use of NMR in solid state research and materials science in the region.
5. Increased visibility of Department of Physics to the European NMR community, to the researchers in Croatia and the region, and to the public.

The new ssNMR laboratory and research group has become recognised by international NMR community. The project and the laboratory are also presented in national media, thus increasing public awareness about scientific and research potential of PDFS and University of Zagreb. Special care was given to present the new laboratory to the possible users in Croatian industry and Small and medium-sized enterprise (SME)s, and encouraging responses from SMEs were received. The project has opened new possibilities for solid-state competitive research in Zagreb. The new ssNMR group in Zagreb became visible at international level and recognised as an unavoidable point in this part of Europe. The solid state research capacities at PDFS are now more than before an important part of European Research Area (ERA) with a large potential to participate in national and international research projects, in particular FP7 and Horizon 2020.

Project results:

WP1: Establishment of the laboratory for ssNMR

The general objective of this WP was to purchase components and to install the ssNMR spectrometer in the laboratory room of the PDFS building, and the preparation of the research staff for the use of the new spectrometer.

Details on the tasks:

WP1.1: Purchase

The ssNMR system is composed of several components, carefully selected for the maximum compatibility and optimal price. The main components of the system are:

1. Wide bore 12 tesla magnet of medium homogeneity (10 ppm / cm), but variable magnetic field has been purchased from Oxford Instruments NanoScience after two international public tenders. The final tests have shown that the magnet is fully compliant with the requested technical specifications.
2. A broadband NMR spectrometer and a power amplifier have been purchased from NMR service. The spectrometer is Tecmag Apollo single channel 5-500 MHz NMR console. The amplifier is Tomco 5-400 MHz, 500 W radio-frequency (RF) amplifier.
3. The racks for the assembly of the components into a self-standing system and the footage for the magnet were manufactured by Croatian SMEs (Epo and Toming).
4. High capacity vacuum pump in order to achieve the base temperature of the system (1.2 K).
5. A function generator for more sensitive low-frequency NMR and Nuclear quadrupole resonance (NQR) measurements.
6. Preamplifiers.

In order to complement the laboratory for a fully operable ssNMR system, the number of purchases has been made from funding of Croatian Government: an additional spectrometer, sample probes, oscilloscopes, network analyser, flow cryostat etc.

WP1.2: Installation

The installation of the NMR system started before the purchased components have arrived by the preparation of the laboratory room and providing suitable connections to all supplies. It continued with check and test measurements (zero field) with the spectrometer which arrived prior to the magnet.

The ssNMR system was completely installed in July 2010. The first tests have shown that the magnet performance satisfies requested specifications needed for the experimental work foreseen in the laboratory. The first spectrum was recorded in August 2010.

However, the long-term helium and nitrogen consumption tests and long-term stability tests have shown that there was a room for improvements and several components have been replaced within the warranty period. At the end of the project, the equipment is working stable in full operation and with reasonably low helium consumption.

The laboratory was officially opened in November 2010 by Minister of Science, Education and Sports of the Republic of Croatia, in the presence of Vice rector of the University of Zagreb, and many other distinguished people from political and scientific life in Croatia. The event has earned broad media coverage.

WP1.3

Preparation of the research staff for the use of the new spectrometer started by the study of advanced theory and practice of NMR measurements, and by visits to EU centres for ssNMR in order to obtain know-how for the optimal run of the NMR spectrometer. Mihael Grbic has visited GHMFL for 7 months, Dalibor Paar has visited IFW for 2 months, and Miroslav Pozek has visited GHMFL for 3 weeks (see WP2). When the Tecmag spectrometer arrived, all the experimental staff was engaged to study the manuals and the first test measurements were performed. It was necessary to purchase a number of small electronic parts, wires, cables, chemicals, tubes etc. The visits of Martin Klanjsek from IJS, Guillaume Lang from IFW, and Steffen Kramer from GHMFL have also been used for intensive on-site exchange of know-how for the use of spectrometer. When the magnet was ready for the factory test, Antonije Dulcic and Miroslav Pozek have visited Oxford Instruments in order to check the magnet performance and to acquire additional know-how for the magnet operation. Young researcher Marko Bosiocic has attended advanced school XV training course in the physics of strongly correlated systems (Salerno, Italy, October 2010). He has also visited LPS for 7 months, and Miroslav Pozek has joined him for 9 days (see WP2). Damir Pajic has visited NMR group at IJS for one month, getting insight into experimental possibilities of that partner group. Due to the abovementioned long-term tests and replacements within the warranty period, it was necessary to purchase more liquid helium than predicted in order to fulfil all necessary tests.

WP2: Mobilisation of human resources

The main objective of this WP is to assure the efficient exchange of know-how and experience between recognised European ssNMR laboratories and the laboratory at PDFS in Zagreb. In this respect, there are foreseen visits of Croatian senior scientists to the European laboratories, medium-term stays of Croatian PhD students in the respective laboratories, a one-year postdoctoral stay of a Croatian scientist, and short visits of the European scientists to the laboratory in Zagreb.

WP2.1:

Twelve visits (total duration eleven months) visits of Croatian senior scientists to the EU laboratories have been fulfilled. In the beginning, the visits were related to the exchange of experience in instrumental optimisation (see WP1.3.) and later visits were related to current development and results of research.

Visit of Dr Dalibor Paar to IFW Dresden, 29 June - 29 July 2009
He has visited the NMR group of Leibniz-Institut für Festkörper und Werkstoffforschung in Dresden. The aim of this visit to one of EU centres for ssNMR is training for the use of the new spectrometer at PDFS and the exchange of experience in instrumental optimisation. During the visit, Dalibor Paar has actively been involved into preparation of the experiment and optimisation of instrumental parameters for the specific ssNMR / NQR measurements of superconductive materials. The aim of these measurements is to understand the mechanism of high-temperature superconductivity. The visit was interrupted for 5 days (5-9 July) in order to visit EUROMAR conference in Gothenburg, Sweden (see WP4.6).

Visit of prof. Dr Miroslav Pozek to LNCMI Grenoble, January 31 - 21 February 2010

SOLENEMAR project coordinator visited the NMR group of Laboratoire National des Champs Magnetiques Intenses (LNCMI / CNRS) in Grenoble, France for three weeks. The aim of the visit was exchange of know-how and experience for the establishment and conduct of solid-state NMR laboratory. The visit of Mr Pozek coincided with the medium-term visit to of his PhD student M. Grbic to the same Laboratory. NMR group at LNCMI is one of the European centres of excellence for ssNMR in high magnetic fields and ultralow temperatures. During the visit, a series of useful discussions was conducted with the hosts (prof. Claude Berthier, Dr Mladen Horvatic and Dr Steffen Kramer), but also with other visitors (e.g. prof. Pietro Carretta from Pavia, Italy). The modalities of future cooperations were considered. In addition, M. Pozek got insight into several sophisticated NMR experiments conducted in the host Laboratory during the visit, with the emphasis to technical peculiarities of these measurements.

Visit of Dr Dalibor Paar to IFW Dresden, 1 February - 1 March 2010

This is the continuation of his first visit to IFW. During the visit, Dalibor Paar has actively been involved into preparation of the experiment and optimisation of instrumental parameters for the measurements of superconductive materials. The aim of these measurements is understanding the mechanism of superconductivity in pnictides.

Visit of professors Antonije Dulcic and Miroslav Pozek to Oxford Instruments, 5-9 May 2010

The 4-day visit of A. Dulcic and M. Pozek to Oxford Instruments was related to acquiring know-how of the magnet operation. During the test, maximum field and maximum sweep rate was tested, the magnet was intentionally quenched and afterwards driven again to the maximum field. Then the field homogeneity and field stability were measured. The magnet has satisfied all the tested parameters.
During the stay in the factory, a number of discussions with magnet construction engineers have been done in order to be better acquainted with the new magnet system and its operation.

Visit of Dr Dalibor Paar to IFW Dresden, 21 February - 29 February 2011

The aim of this visit was further exchange of experience in instrumental optimisation, and to arrange a visit of NMR experts from Dresden to PDFS in Zagreb for on-site optimisation and adjustment of the NMR equipment.

During this visit ssNMR / NQR measurements of superconducting materials have been continued. The important question is the mechanism of the coexistence of static magnetism and superconductivity. After the visit those measurements were continued in ssNMR laboratory at PDFS.

Visit of prof. Dr Miroslav Pozek to LPS, Orzay, 2-10 July 2011

Prof. Dr Miroslav Pozek has visited the NMR group of Laboratoire de Physique des Solides (LPS / CNRS) at the University Paris-Sud Orzay (France). The aim of the visit was to get acquainted with the solid-state NMR laboratory in one of the European centres of excellence for solid state physics. The visit of Mr Pozek coincided with the visit of his PhD student M. Bosiocic to the same laboratory.

During the visit, a series of useful discussions were conducted with the hosts (prof. Philipe Mendels, Dr Fabrice Bert, Dr Jeffrey Quilliam). M. Pozek was given access to several experimental setups of the host laboratory. The modalities of future cooperation were considered, especially the topic of the mid-term visit of Marko Bosiocic to the same laboratory planned for autumn and winter same year. In addition, the last organisational issues of the 2nd Trogir workshop have been discussed and settled.

Visit of prof. Dr Hrvoje Buljan to IFW Dresden, 19 June - 29 July 2011

Prof. Dr Hrvoje Buljan has visited the NMR group at Leibniz-Institut für Festkörper und Werkstoffforschung, Dresden, led by Dr Hans. J. Grafe. The aim of the visit was first getting acquainted with the theoretical aspects of research in the host solid-state NMR laboratory, and second exploring the possibilities for extending a research topic on dynamics of so-called Loschmidt echoes, that Prof. Hrvoje Buljan is interested in, to NMR systems studied within the groups of the SOLENEMAR project. The experiments of Loschmidt echoes are particularly interesting today in the context of low dimensional quantum systems and they are performed to some extent in ultra-cold atomic gases. However, experiments in those systems are quite hard and NMR could be the technique that could have advantages over other techniques. These studies are currently underway. The visit of H. Buljan partially coincided with the visit of Prof. Dalibor Paar to the same laboratory.

Visit of Dr Dalibor Paar to IFW Dresden, 27 June - 22 July 2011

The aim of this visit was to get experience of using ssNMR technique on different type of systems that we were not measured before, such as geological samples, in particular speleothems. Speleothems can grow for thousands of years. During that time they encode palaeoclimatic information in their geometry and geochemistry. A great work has been done over the past decade with a variety of techniques that have been used to investigate trace elements included in the structure of speleothems (CaCO3) or isolated within the crystal lattice. ssNMR can bring new information for high resolution palaeoclimate and palaeoenvironmental reconstruction. The aim of our work is to determine the possibility of investigating other trace elements in the structure of speleothems such as 23Na and 27Al using ssNMR in order to contribute to the understanding of the conditions of their formation.

Visit of Dr Damir Pajic to IJS Ljubljana, 1-29 July 2011

Assistant professor Dr Damir Pajic has visited two groups in Ljubljana (Slovenia): NMR group at Josef Stefan Institute (JSI) and NQR group at Institute of Mathematics, Physics and Mechanics (IMFM). The aim of the visit was to enable the transfer of knowledge and experience within the current solid-state NMR research in one of the successful European centres with long tradition in this field. The visit was partly devoted to learning the basics of NMR experiments, applied in several case studies, and including different pulse techniques. In this part especially useful were the discussions with prof. Dr Jani Dolinsek, leader of NMR group, as well as with prof. Dr Zvonko Trontelj, leader of NQR group, who gave the hints to the literature study. As a further step, their recent published works were the framework for discussions in which other team members explained more specific investigation and results, and helped to embed it into broader context. For example, Stane Vrtnik shared his expertise in NMR of quasicrystals and other solid-state systems, and Dr Janko Luznik and Dr Janes Pirnat shared their knowledge and expertise in NQR of different substances currently investigated, with special emphasis on improvements of the experimental set-up. Also, NQR group presented some non-conventional experimental set-up featured with enhanced sensitivity.

Further useful comments and hints from above mentioned researchers were regarding the recently started research in the Zagreb laboratory. The possibilities of future cooperation were considered, and the needs in the field of multiferroics and metallo-organic frameworks were discussed.

Altogether, this one month stay was useful for the future work of Dr Pajic in field of NMR because of extending the basic knowledge, learning through discussions of recent published work of the two renowned groups, instructions for the research in domestic laboratory, and planning of future collaboration.

Visit of Dr Dalibor Paar to IFW Dresden, 30 January - 27 February 2012

The aim of this visit was further training for the use of the new spectrometer at PDFS and the exchange of experience in instrumental optimisation, especially getting experience of ssNMR measurements of superconducting iron pnictides samples. This is a continuation of a previous collaboration in this subject.

Visit of prof. Dr Hrvoje Buljan to IFW Dresden, 8-21 July 2012

During the visit to the Leibniz Institute for Solid State and Materials Research, Dresden, Prof. Hrvoje Buljan has given talks titled 'Plasmons in graphene: fundamental properties and potential applications' and exact studies of non-equilibrium dynamics in 1D Bose gases' to describe in more details some of the topics of his research conducted at the PDFS. The discussions of these and other topics were very inspiring and opened up ideas for possible new directions of research.

In addition, during the visit to Dresden Prof. Buljan used the opportunity to also visit the Max Planck Institute for the Physics of Complex Systems and the Helmholts C Dresden-Rossendorf and discussed scientific problems of mutual interest with the scientists there.

Visit of Dr Mihael Grbic to LNCMI Grenoble, 1 May - 30 June and 3-31 August 2012

After finishing his postdoctoral stay, Dr Mihael Grbic evolved into an experienced researcher in the field of ssNMR. He visited LNCMI in order to discuss and define further work on the pinwheel kagomecompound RbÂ-2Cu3SnF12 and to run measurement in high-magnetic field at LNCMI. The acquired data brought about new findings and stimulated a lot of discussions which help to understand this system.

During the stay, he was also holding a position of a local contact to help visiting scientists do their research using the equipment of the ssNMR laboratory. This experience was extremely useful for his future work at PDFS as a senior scientist, since the position provides a possibility for direct-learning from other research groups around the world.

WP2.2: Five medium-term stays of PhD students from Zagreb to EU partner laboratories were fulfilled (total duration 14 months):

Visits of Mihael Grbic to LNCMI Grenoble, October - December 2009 and January - April 2010

He has visited the NMR group of prof. Dr C. Berthier in Laboratoire National des Champs Magnetiques Intenses (LNCMI / CNRS) in Grenoble, France (former GHMFL) as a part of his preparation for the use of ssNMR technique in the new laboratory at PDFS, and the first scientific training in the technique. He has received useful knowledge on the principles of the NMR technique, technical insight in creation of a high-quality NMR probe, and participated in some experiments of the host group. His local supervisor, Dr M. Horvatic, enabled him to obtain all the knowledge necessary to understand the operation of a typical ssNMR spectrometer, as well as the underlying physics of the experimental technique when it is used in research. Also, M. Grbic got knowledge on many tricks-of-the-trade for optimisation of a typical measurement process and data acquisition.

Dr S. Kramer from the same group has shown him the details important for building and running a high-quality NMR probe. In parallel, M. Grbic designed and constructed a specific low-loss NMR probe.

During his stay, there were several experiments performed by the members of the ssNMR group themselves, or by visiting scientists, and he participated on some of them, thus learning different ways to approach a certain problem and obtain valuable results. He has intensively participated in experiments ran by Dr S. Mukhopadhyay (post-doc student at LNCMI), and prof. Dr V. Mitrovic (visiting scientist from Brown University).

Visits of Marko Bosiocic to LPS Orsay, June 2011 - July 2012 (3 visits, in total 7 months)

He visited NMR group at Laboratoire de Physique des Solides in Orsay (France), at the University Paris-Sud (UPS) 11, led by Prof. Dr Philippe Mendels.
Marko Bosiocic worked under supervision of assistant professor Dr Fabrice Bert, post-doc Jefferey Quilliam and Prof. Dr Philippe Mendels. He joined the research of Ba3CuSb2O9 compound, which is new candidate for a frustrated spin liquid system. He was also investigating new one-dimensional compound LiCuSbO4, a frustrated system with many interesting properties. Discussions about different behaviour of NMR spectra in general were very useful and can be applied to broad class of magnetic insulators.
M. Bosiocic was also simulating NMR spectra with quadrupolar interaction. He got acquainted with hardware and software which were mainly made in the host laboratory. A lot of gained knowledge can be used to improve technical setup in newly founded ssNMR in Zagreb.

Between the visits, a significant part of investigations were done in Zagreb, which proves that already existing ssNMR capacities is Zagreb are powerful enough to join and contribute to hot scientific topics on the world scale.

Between the 2nd and the 3rd visits M. Bosiocic was invited to participate in ISIS SR school, at Rutherford Appleton Laboratory in UK and later for actual SR experiment on the LiCuSbO4 sample. Both of these stays were covered by ISIS grants, and they additionally improved his experience in SR method (which is tightly bound to NMR) and in extremely low temperature measurements necessary for research of strongly correlated systems.

WP2.3

Fourteen visits of EU partners to Zagreb have been completed. Each stay included open lecture and a few days of intensive discussions with the group members. In addition to this, Dr Steffen Krämer gave a series of lectures on NMR for postgraduate students, while Dr Hannes Kohne and professor Hadrien Mayaffre helped in developing software for data acquisition and processing. Dr Fransiska Hammerath actively helped in the running experiments. Not counted in this, it is worth noting that all leaders of partner groups gave open lectures the day after the kick-off meeting (prof. H. Alloul, prof. P. Mendels, prof. J. Dolinsek, Dr M. Horvatic, and Dr H. J. Grafe). Here is the list of visits dedicated to on-site transfer of knowledge to the members of ssNMR laboratory:

Dr Martin Klanjsek from Josef Stefan Insititute, Ljubljana has visited PDFS from May 3 to May 5, 2010. The aim of his visit was transfer of knowledge and experience between NMR groups in Ljubljana and Zagreb, and talks about future cooperation. Dr Klanjsek also gave a seminar â??NMR in spin Luttinger liquidsâ?œ on Tuesday, May 4th, at 14:15 in the large lecture hall of the Physics Department.

Dr Guillaume Lang from Leibniz Institut für Festkörper und Werkstoffmaterialen, Dresden has visited PDFS from 30 May - 4 June 2010. Besides transfer of knowledge and experience between two NMR and discussions about future cooperation in NMR research of strongly correlated electron systems, Dr Lang gave a seminar 'Probing the local properties of correlated electron systems: application to cobaltites and iron pnictides' on Tuesday, 1 June at 14:15 in the large lecture hall of the Physics Department.

Dr Steffen Kramer from Laboratoire National des Champs Magnetiques Intenses (LNCMI / CNRS), formerly Grenoble high Magnetic Field Laboratory (GHMFL), has visited PDFS three times.

The first visit was on 1-4 September 2010. This was the first visit of a European partner to the newly established ssNMR laboratory after the installation of 12 tesla magnet in July. The aim of this visit was to get acquainted with the experimental setup in Zagreb and to run the test measurements. Having large experimental NMR experience, Dr Kramer was able to point to the main shortages of the setup and to suggest the steps towards better performance. Intensive discussions with all members of the Laboratory in Zagreb helped in transfer of experience and knowledge between LNCMI and PDFS.

The second visit was on 12-16 December 2010. Dr Kramer gave a lecture titled 'Topics and techniques in NMR spectroscopy at ultra-high magnetic fields: from condensed matter physics to half-integer quadrupolar nuclei' where he pointed out the wide spectrum of application of NMR technique in solid state physics. Beside the talk, Dr Kramer participated in actual NMR research of deutereted ethanol, topic investigated in collaboration with Rudjer Boskovic Institute. His advices were very useful, from theoretical aspects of process in samples to optimisation of experimental parameters. Dr Kramer also discussed results of NMR research of bromine compounds, topic investigated by prof. M. Pozek and B. Peric from Rudjer Boskovic Institute. In conclusion, we can emphasise that visit of Dr Krämer to PDFS was very useful. All members of ssNMR group, from students to the more experienced scientist, had an opportunity to learn directly from an experienced scientist in the field. Dr Kramer suggested several ideas that would lead to further optimisation of equipment.

The third visit was in the period 22-28 January 2012. The main task of Dr Kramer during this visit was giving a course 'Concepts of pulsed NMR spectroscopy'. The course was designed for PhD students of condensed matter physics willing to work with NMR or at least to understand the NMR results. Duration of the course was 10 hours. There were 12 students regularly attending the course, and they were credited with 2 ECTS points. In addition to the PhD students, additional 11 physicists from PDFS, Rudjer Boskovic Institute, and Institute of Physics have regularly attended the lectures and took part in discussions afterwards. Dr Kramer also discussed results of current NMR research at PDFS on magnetic materials, and proposed additional measurements and interpretation of the results.

Dr Mladen Horvatic from Laboratoire National des Champs Magnetiques Intenses (LNCMI / CNRS), formerly Grenoble high Magnetic Field Laboratory (GHMFL), has visited PDFS on 31 January - 5 February 2011. He was a member of the jury for the PhD Thesis of Mihael Grbic. The thesis was publicly defended on 2 February. In addition, Dr Horvatic gave a lecture 'NMR and physics of quantum spin systems in (strong) magnetic field' (in Croatian: 'NMR i fisika kvantnih spinskih sustava u (jakom) magnetskom polju'). The rest of his stay in Zagreb, Dr Horvatic spent mainly in the new laboratory for ssNMR. He has discussed previously obtained experimental results, and their interpretation. He also examined possible causes of experimental ambiguities and gave several hints how to overcome them. Intensive discussions with all members of the Laboratory in Zagreb helped in transfer of experience and knowledge between LNCMI and PDFS.

Dr Seung-Ho Baek from Leibnis Institut für Festkörper und Werkstoffmaterialen, Dresden, has visited PDFS on 2-6 May 2011. Dr Baek gave a lecture 'Role of anisotropic spin fluctuations in '115' heavy fermion superconductors'. The rest of his stay in Zagreb, Dr Baek took part in several discussions with SOLENEMAR project members, especially prof. Slaven Barisic and prof. Antonije Dulcic, which might lead to future collaborations. Dr Baek has also spent considerable time in the new laboratory for ssNMR, discussing the details of experimental setup with prof. Miroslav Pozek, Dr Damir Pajic, Dr Brajesh Pandey, Marko Bosiocic, and three students who currently conduct seminar works in the Laboratory. He also instructed the students how to prepare NMR coil and NMR probe in order to avoid unwanted experimental artefacts.

Dr Hannes Kohne from Technical institute in Dresden, Germany, has visited PDFS on 10-21 September 2011. Dr Kohne gave a lecture 'Quantum critical dynamics in the one-dimensional spin chain systems Cu(C4H4N2)(NO3)2 and (phsH)2CuCl4H2O'. In addition to the seminar, Dr Kohne made a lot of effort to improve the performance of the NMR spectrometer in the new ssNMR laboratory. He has installed a software for field sweep control and data analysis (originally developed in TU Dresden) to the computers in the Laboratory, and adjusted the software for operation with the experimental setup in Zagreb. Dr Kohne also took part in several discussions with SOLENEMAR project members and other solid-state physicists in Zagreb interested to his work.

Dr Fransiska Hammerath from Leibniz Institute for Solid State and Materials Research (IFW) Dresden, Germany, has visited PDFS two times.

The first visit was on November 13-19, 2011. She gave a lecture 'Unusual NMR line broadening and spin gap in the Sigsag S=1/2 spin chain compound Sr1-xCaxCuO2'. The rest of the time, Fransiska Hammerath was helping in improvement of performance of the NMR spectrometer in the new ssNMR laboratory. She was testing software for magnetic field sweep control and data analysis. She also took part in several discussions with SOLENEMAR project members and other solid-state physicists in Zagreb interested to her work.

The second visit was on 22-27 January 2012. This time Dr Hammerath actively took part in the current measurements in the ssNMR laboratory in Zagreb by supervising younger researchers during the measurements. She has given several suggestions for improvement of the measurement setup and data analysis. She also took part in several discussions with SOLENEMAR project members and other solid-state physicists in Zagreb interested to her work. Discussions on possibilities for future cooperation have shown that there is wide area of common topics in the field of strongly correlated systems, but also the topics connected to the soft matter and glassy systems.

Professor Henri Alloul from Laboratoire de Physique des Solides, Universite Paris Sud (LPS), Orsay, France, has visited PDFS on 21 – 27 March 2012. During the visit to the newly established Laboratory for ssNMR at PDFS, he was especially engaged in discussions with younger members of the Laboratory (PhD student Damjan Pelc and master student Tonci Cvitanic) on technical aspects of sensitive NMR measurements. He also conducted long discussions with prof. Antonije Dulcic on transport and NMR results on high temperature cuprate superconductors. This visit was connected with the attendance to the PLDC conference in Zagreb (25-28 March), where professor Alluol gave an invited lecture entitled 'Evidence for distinct ranges and gaps for the superconductivity and the pseudogap from high field transport measurements of the superconducting fluctuations in YBa2Cu3O6+x'. During the conference we have discussed possibilities of future collaborations.

Professor Amit Keren from Technion Institute of Technology, Haifa, Israel, has visited PDFS on 22-27 March 2012. It was the opportunity to present the newly established Laboratory for ssNMR at PDFS to the experienced guest from Israel. Professor Keren has brought many samples grown at his Institute and he took part in NMR experiments which we immediately started on his samples. He also took part in many discussions with members of the Laboratory and with other solid-state physicists at PDFS. Visit of prof. Keren was connected with the attendance to the PLDC conference in Zagreb (25-28 March), where he gave lecture entitled 'A magnetic analogue of the isotope effect in cuprates'.

This visit has established collaboration between PDFS and the laboratory of professor Keren at Technion. At a moment, the collaboration is purely scientific (investigation of the same topic with complementary methods) but there are mutual intentions to make the collaboration institutionalised.

Professor Hadrien Mayaffre from Universite Joseph Fourierre and LNCMI, Grenoble, France, has visited PDFS on 6-8 June 2012. On the first day of his visit he gave a seminar entitled 'Quantum critical points and field induced phase transitions in quantum spin systems: examples of NMR studies on spin ladders' which induced many discussions afterwards. The remaining time of his visit he spent in the newly established laboratory for ssNMR at PDFS. The main task was the implementation of the software, originally written by professor Mayaffre for the Grenoble NMR laboratory, in the Zagreb NMR laboratory. Professor Mayaffre has on-site written several subroutines in order to make software functional at PDFS. He was especially engaged in discussions with younger members of the Laboratory (PhD student Damjan Pelc and master student Tonci Cvitanic) on technical aspects of the software, and he taught them how to make future adjustments if necessary. Thanks to this visit, the new NMR laboratory is now equipped with an excellent software for data acquisition and manipulation.

Dr Hans-Joachim Grafe, from Leibniz Institute for Solid State and Materials Research (IFW), Dresden visited PDFS on 25-29 June, 2012. Dr Grafe gave a lecture 'New NMR results in the prototypical high temperature superconductors La2-xSrxCuO4 and YBa2Cu3Oy'. The lecture initiated scientific discussions about new results in high temperature cuprate superconductors with several project members (Slaven Barisic, Antonije Dulcic, Miroslav Pozek, Damjan Pelc) and students. In addition to the seminar, Dr Grafe discussed the future cooperation between Dresden and Zagreb ssNMR groups. As a part of this cooperation, the samples of iron pnictide superconductors (new class of superconductors discovered in 2008) that are prepared in Dresden will be measured during 2012 in ssNMR laboratory in Zagreb.

WP2.4

A one-year postdoctoral stay of Croatian scientist Mihael Grbic at LNCMI Grenoble.

Mihael Grbic held a postdoctoral position in Laboratoire National des Champs Magneiques Intenses (LNCMI), Grenoble from March 2011 to February 2012.
During the postdoctoral stay he was doing research on the compound Rb¬2Cu3SnF12 (also known as pinwheel kagome) under supervision of Dr Mladen Horvatic. The system is formed of frustrated copper spins distributed on a kagome lattice. Upon cooling, the spins enter a non-magnetic singlet ground state and form a characteristic pinwheel pattern which breaks the symmetry of the lattice forming a Valence bond solid state (VBS). This is interesting for research because the VBS state is one of theoretically predicted but unexplored ground states of a frustrated magnetic system. By using NMR techniques he was supposed to obtain the information on the static spin structure, and the magnetic field dependence of the singlet-triplet excitation energy gap. The data were acquired with an NMR probe built during his previous stay at LNCMI. This was in fact crucial for easy data acquisition and also enabled additional development of the probe design. Indeed, he found that the spin structure is unusual distributed in a way not typical for a singlet state. The singlet-triplet gap shows that it cannot be closed by the magnetic field, with a large residual value. This is quite a new result in comparison to previously obtained data at low magnetic field values.

Throughout the postdoctoral stay Mihael Grbic has learned a lot about many other aspects of NMR research: cryogenic techniques (down to 0.05 K), electronics, applicability of the technique things which are usually not presented in one's career development but proves to be very important for a newly founded laboratory. This valuable know-how is already being implemented in the ssNMR laboratory in Zagreb, and will surely boost its potential as a European research facility.

WP3: Employment

This WP serves to increase the engagement of human potentials for the work on the project by the reimbursement of salary to the already employed scientists at PDFS, by employment of young experienced researcher, and by employment of postdoctoral researchers.

WP3.1: Reimbursement of salary for 11 existing scientists in the ssNMR laboratory. This WP financially covers efforts for conduction of other WPs for the whole project period.

WP3.2

New employment

Dalibor Paar has been employed as assistant professor at PDFS in June 2009.
Marko Bosiocic has been employed as young researcher at PDFS in January 2011.
Damir Pajic has been employed as assistant professor at PDFS in May 2011.
Damjan Pelc has been employed as young researcher at PDFS in February 2012.

These positions are financed by the Croatian Ministry of Science, Education and Sports, but the researchers are partly working for SOLENEMAR and these efforts are reimbursed in WP3.1

WP3.3: One-year postdoctoral stay of an experienced scientist in Zagreb.

The world-wide announcement for the open postdoctoral position was spread through several channels. At this competition we have selected Dr Brajesh Pandey, an experienced scientist from Kanpur, India. His employment started in March 2011. Dr Pandey has intensively worked on the synthesis of magnetic nanoparticles and their characterisation by X-ray and NMR methods, thus bringing a new value to the PDFS. After 8 months he got a position in Brazil, where he continued investigation of the nanoparticles by Mossbauer spectroscopy. His investigations will lead to a joint publication between PDFS-Zagreb and CBPF - Rio de Janeiro (in preparation).

WP4: Dissemination

The purpose of this work package is to increase the visibility of PDFS within stakeholders in Croatia, south-eastern Europe and EU, and in the industry, SMEs and general public. The increased visibility of PDFS shall be fulfilled by a number of actions, starting with the creation of a devoted web page, and followed by the organisation of workshops, stimulation of young researchers from the region, seminars and round table discussions for industry and SMEs.

WP4.1

The web page of the project http://nmr.phy.hr was created before its official start in Croatian and English language. The web page has regularly informed the public about the project activities. It was well visited.

In the beginning of the project, Croatian pages have been visited 400 times monthly, while in the second half of the project it was visited more than 1 000 times a month. The English pages are visited in average 250 times a month. The pages will remain active as official site of the Laboratory after the project closure.

WP4.2

Mobilisation of the media was very successful. Even before its official start, the project has been presented at national TV and 7 national newspapers. During the project execution, five occasions have attracted attention of the media:

a) The public was also informed about the kick-off meeting and the start of the project (national-level newspapers and their web services).
b) The first Workshop in Trogir was followed by press release, TV coverage on a national level, radio coverage on local level and news on web portals.
c) On occasion of the official opening of the laboratory in November 2010, the event was covered by press release, TV coverage on a national level, a full article in newspaper on a national level and several short news in newspapers.
d) Following the first series of seminars for SME, Croatian radio has broadcasted an interview with Miroslav Pozek, and on the occasion of 100th anniversary of superconductivity Croatian television has broadcasted a story about investigation of superconductors within SOLENEMAR.
e) Successful conclusion of the project with the prestigious publication and success of young researchers has been followed by a press release, presented in the central informative broadcast Dnevnik of the first program of the Croatian National Television (2 minutes), and an interview with three authors about the new discovery and about the SOLENEMAR project on Croatian radio (10 minutes).

Links to video and audio records of TV and radio broadcasts are collected on the web page (see http://nmr.phy.hr/en/media online for further details).

To this purpose ten grants were available from the project to cover all the expenses at the conference for selected young researchers.

The program of the workshop with abstracts is presented in the Abstract book, and on the workshop web page (see http://www.phy.hr/trogir2010 online for further details).

The 2nd international workshop on 'Recent advances in broad-band solid-state NMR of correlated electronic systems' took place on 4-9 September 2011, in Trogir, Croatia. The workshop brought together 64 NMR experts and those interested in the local properties of complex materials. The aim of the workshop was to stimulate interest in NMR measurements and in broad-band NMR techniques.

The workshop encompassed the following topics: high-Tc superconductors, fullerides and pnictides, quantum magnetism, spin liquids, heavy fermion conductors, actinides and skutterudites, as well as advances in broad-band NMR techniques.

A specific aim of the workshop was to foster the development of NMR expertise among young researchers, which is one of the formal goals of the above-mentioned SOLENEMAR project. To this purpose ten grants were available from the project to cover all the expenses at the conference for selected young researchers.

The program of the workshop with abstracts is presented in the abstract book (attached to this report), and on the workshop web page (see http://www.phy.hr/trogir2011 online for further details), where the abstract book and slides of 29 lectures presented on the workshop are available to conference participants under password protection.

There is a common opinion of all participants that a workshop of that format for broadband NMR community was missing in Europe, and that this series of workshops should be continued on a biannual or triennial rhythm.

WP4.4: International competitive opening for the attendance of young researchers and PhD students to the 1st Trogir workshop was announced in February 2010 on the web page (see http://www.phy.hr/trogir2010/youngresearchers.html online for further details) and by worldwide e-mail advertisement. Out of 18 candidates, 11 young researchers have been given grants for the attendance to the workshop (accommodation, registration fee and partially travel expenses).

International competitive opening for the attendance of young researchers and PhD students to the 2nd Trogir workshop was announced in February 2011 on the web page (see http://www.phy.hr/trogir2011/youngresearchers.html online for further details) and by worldwide e-mail advertisement. Out of 15 candidates, 11 young researchers have been given grants for the attendance to the workshop (accommodation, registration fee and partially travel expenses).

The interested young candidates were asked to submit their curriculum vitae, list of publications, letter of intent and at least one letter of reference. The grant awards committee, which handled the applications and made the final list, has taken into account that PhD students at the beginning of their careers may have no publications. An important criterion was the connection of the candidate's future work and the field of NMR.

WP4.5

Two series of seminars for the people from industry and SMEs have been organised

The first series titled 'Physics in application' was held at the Department of Physics on 22 February 2011. Four speakers were invited to talk about the application of experimental techniques used by physicists in their everyday research, in industry. The first topic covered was NMR/NQR, and the talk was held by Prof. Dr Miroslav Pozek (more focus was given to food industry because of the structure of the audience). The other topics were on EPR held by Prof. Dr Srecko Valic, laser physics held by Dr Slobodan Milosevic, and on using accelerator beams held by Dr Milko Jaksic.

Amongst the attendants of the seminar were representatives from one of our largest food industry Agrokor: a member of the office for patents, a person from a pharmaceutical company, small wine makers, a producer of pumpkin oil, small metal-oriented enterprises, and representatives from hospitals which use physics in clinical treatments of patients, but also a number of high-school physics teachers interested in topics. The seminars were well received by the audience and there were lots of questions and discussions. After the talks we have held a small reception were discussions continued.

The second series of seminars was organised in May and June 2012, by using a different approach than the first series. This time we have targeted several small and medium enterprises and visited them to give seminars with greater focus on the particular subjects that these SMEs are interested. This approach brought about more discussions and ideas for further cooperation.

First, we visited Svijesda d.d. (see http://www.svijesda.hr/ online for further details), which is one of the greatest producers of oil, margarine, mayonnaise and similar food products. They have a commercial NMR in their lab that is used to control the quality of food on a daily basis. However, they were particularly interested in the possibility of measuring diffusion with NMR, which is something that is possible in our NMR lab, and not in their company. The group visiting Svijesda d.d. from the SOLENEMAR project was Prof. Miroslav Pozek, Prof. Hrvoje Buljan and Damjan Pelc (PhD student). In order to present our capacity and the possibilities of our lab, we have presented a seminar titled 'Diffusion NMR: potential for applications'. The visit was very successful. We have exchanged ideas and established a firm contact that will be used in the future.

Professor Dulcic presenting an optical way of measuring temperature without contact at the Koncar institute
Second, we have contacted Koncar Electrical Engineering Institute (see http://www.koncar-institut.hr/ online for further details) which is officially an SME. They are very interested in collaborating with the Department of Physics and have organised for us to give three short seminars at their location. The heads of several departments of the institute were in the audience. The seminars were held by Prof. Pozek (title: 'Dissolving the microscopic model of conductivity in an ionic conductor Cu2HgI4 with NMR'), Prof. A. Dulcic: (title: 'Luminiscence for noncontact thermal measurements), and Prof. H. Buljan (title: Molding the flow of light in photonic structures'), all three from the SOLENEMAR project. After the seminars a long discussion followed where we were provided with the questions from the Koncar employees about the possibility to tackle some of the problems they encounter regarding optical sensing of concentrations of some substances within the transformer oil. These seminars and discussions, together with the contact that preceded this meeting led to a joint application for SME-academia project that is submitted to one of the open calls within Croatia (BICRO). One month after this meeting we were invited to visit Koncar Institute again in order to discuss possible solutions for some new issues that arose in the production. Hence, the management of Koncar Institute has found PDFS to be a suitable partner for collaboration. We are looking forward to fruitful collaboration with this SME. In that respect, we can regard the contacts that we made as excellent.

Third, we have visited the Elektrosanitarij company in Samobor (see http://www.elektrosanitarij.hr online for further details) which produces versatile types of furnaces. The company already has several products made for the Rudjer Boskovic Institute and the University of Zagreb even though most of their products are made for industry. They are potential partners for the academia because they are capable of producing furnaces for production of novel materials (e.g. ceramics). After presenting some of the potentials of our department, we have underlined the possible types of collaboration with this enterprise.

WP4.6: Attendance to the EUROMAR and other conferences in order to make ssNMR in Zagreb visible

EUROMAR 2009 conference, Gothenborg (5-9 July 2009)
Dalibor Paar presented the work NMR / NQR Investigations of Superconducting Ferropnictides. The work has received considerable interest. In addition, during the conference D. Paar has spoken to several experts in broadband NMR investigations about the new laboratory in Zagreb, and especially presented the project SOLENEMAR to professor Peter Jeglic from Ljubljana.

M2S-HTSC 2009, Tokyo (7-12 September 2009)
Dalibor Paar presented the work titled 'NMR studies of electronic properties of superconducting LaO1-xFxFeAs'. The aim of presentation on this conference was to make ssNMR in Zagreb visible to the international solid state physics community. During the presentation, several scientists expressed interest in the existence of the emerging NMR group in Croatia.

Joint EUROMAR / ISMAR conference, Florence (4-9 July 2010)
Miroslav Pozek has presented poster titled 'New experimental facility for broadband ssNMR and NQR' in Zagreb, Croatia. The aim of the presentation was to inform the World NMR community about the establishment of the new laboratory for broadband NMR spectroscopy. Technical characteristics of the experimental setup have been presented. The open postdoctoral positions have been announced. The interests for scientific cooperation have been expressed.

The presentation has attracted a considerable interest of conference attendants. Discussions about possible cooperation were carried on with participants from Brazil, France, Germany, Italy, Slovenia and the USA.

Ivan Kupcic presented the work â?œComparison of the occupation number and in La2-xSrxCuO4 estimated by NMR / NQR and ARPES probes. The presented work has attracted a considerable attention, but the interested scientists have also shown a large interest for the SOLENEMAR project.

ALT100 conference, Kazan, Russia (21-25 June 2011)
Miroslav Pozek has presented the first scientific results obtained using the equipment purchased within SOLENEMAR at the international conference 'ALT100 - resonances in condensed matter'. The title of the presentation was 'Static ssNMR investigation of niobium cluster (Nb6Br12(H2O)6)(HgBr4) 12H2O. Besides its scientific importance, the presentation has shown some technical abilities of the ssNMR laboratory in Zagreb. The aim of the presentation was to inform the condensed matter NMR community about the establishment of the new laboratory for broadband NMR spectroscopy, and to express interests for scientific cooperation.

The presentation has attracted considerable interest of conference attendants. Most of discussions have been conducted with professor H. Nakamura from Kyoto (Japan), and with Russian scientist: professor I. Mukhamedshin from Kazan, professor O. Vyaselev from Chernogolovka, Dr V. Ogloblichev from Ekaterinburg, and Dr R. Gainov from Kazan. There is mutual interest to start cooperation with all these scientific groups.

During the conference, M. Pozek has visited all the magnetic resonances laboratories at the Institute of Physics of the Kazan Federal University. It is worth noting that some pioneering works in magnetic resonances have been done in Kazan, 67 years ago, and the strong scientific school still exists. Professor Mukhamedshin is head of two laboratories, and most of the discussions have been done during the visit to those laboratories.

EUROMAR 2011 conference, Frankfurt (21-25 August 2011)

SOLENEMAR has been presented at European magnetic resonance conference EUROMAR2011 in Frankfurt (Germany), with a strong delegation. Five contributions showing five diverse topics studied in the new NMR laboratory in Zagreb have been presented. Work phase transition and conductivity mechanism in the ionic conductor Cu2HgI4� was presented by prof. Miroslav Pozek. Topic 'NMR analysis of trace elements in speleothems' was presented by Dr Dalibor Paar. Topic 'Static ssNMR and NQR investigation of hexanuclear metallic clusters' was presented by Marko Bosiocic. Work 'A paramagnetic DPPH crystal deposited on the crystal of single molecular magnet; EPR evidence on the proximity effect' was presented by Dr Boris Rakvin, SOLENEMAR project partner. Topic 'Anomalous diffusion in gelatin gelation' was presented by Damjan Pelc, graduate student in ssNMR laboratory.

The attendance to the largest European magnetic resonance conference with five diverse presentations made the new ssNMR laboratory visible in the magnetic resonance community, Zagreb with its ssNMR capacity became an unavoidable spot on the European magnetic resonance map.

The presentations have attracted considerable interest of conference attendants. The results have been discussed with many scientists who found them very interesting. In addition, conversations about possible future cooperation have been held with prof. Haase from Leipzig, prof. Lubits and prof. Mobius from Malheim, and prof. Dolinsek from Ljubljana.

Graduate student Damjan Pelc and PhD student Marko Bosiocic benefited strongly from the attendance to such a large conference, getting insight into top research topics in magnetic resonances.

JSMD 2011, Bonn (15-18 November 2011)

SOLENEMAR has been presented at the Julich Soft Matter Days (JSMD) 2011 in Bonn, Germany, with a poster contribution presenting results obtained in the new NMR laboratory in Zagreb. The poster 'Mesoscale organisation in the gelation of gelatin' was presented by Damjan Pelc, young researcher in ssNMR laboratory. The presented work highlighted the capabilities of the laboratory for measuring macromolecular dynamics with the pulsed-field-gradient NMR technique, for which a special probe was developed. As the research is still unpublished, it aroused considerable interest in the soft matter community. The conference proved very fruitful for discussions, and the presented broad range of current soft matter research was useful for devising new directions of investigation to be performed with the high-gradient instrumentation in the ssNMR laboratory.

WP5: Management

SOLENEMAR is a single beneficiary project and the management and decision-making structure of the project is simple. The main purpose of this work package was ensuring the smooth project flow and coordination of all project activities. However, several management activities had larger influences to the project results than just a coordination and administration.

All the partners who took part in the kick-off meeting (prof. H. Alloul, prof. P. Mendels, prof. J. Dolinsek, Dr M. Horvatic, and Dr H. J. Grafe), held open lectures a day after the kick-off meeting. The lectures and the discussions afterwards served as a good start for the exchange of experience between partner institutions and the NMR group at PDFS. The lectures, however, attracted considerable attention of scientists not directly involved into the project, hence triggering the better communications among stakeholders in Zagreb and Croatia.
