Skyrmion devices and their high frequency dynamics

Final Report Summary - SKYHIGH (Skyrmion devices and their high frequency dynamics)

The SKYHIGH project investigated the high frequency properties of nanoscale magnetic materials, with a particular focus on those that possess a chiral Dzyaloshinskii-Moriya interaction by virtue of their structural inversion asymmetry. The mechanism was to provide a fellowship for Dr Satoshi Sugimoto, a PhD graduate of the University of Tokyo, to carry out research and training for a period of two years at the University of Leeds in the UK. Dr Sugimoto is an acknowledged expert on high frequency experimental methods for the study of magnetization dynamics in magnetic nanostructures.
Accomplishments of the project include: the development of a high-frequency measurement system at Leeds capable of electrically detecting magnetization dynamics electrically through rectification effects; providing transfer of knowledge into the EU by training doctoral and postdoctoral researcher in Leeds in its use, giving talks and seminars both at Leeds and externally, offering research projects and supervision to undergraduates in Leeds, attending and presenting results at conferences, and visiting other laboratories to perform joint experiments; and developing the spin-wave Doppler measurement technique to measure the spin polarization of multilayers, yielding new understanding of the effects of interfaces. Other work carried out during the project will be carried on to yield further results on the electrical transport properties of chiral germanide thin films.
The results achieved will have impact in the ITC hardware sector, where magnetic materials are used to store data. High-performance magnetic memories will require fast response times in the materials from which they are constructed in order to be able to operate at sufficiently high speed.
