Deliverables
The aim of the project was to determine the mass renormalisation mechanisms in organic metals and other interactions both experimentally and theoretically. Work was carried out at five institutes. Highlights included the first observation of a completely new magnetic resonance, the Fermi-surface traversal resonance, the first measurement of antiferromagnetic resonance in a BEDT-TTF charge-transfer salt, and the first proof for charge-density waves in BEDT-TTF salts.
Clarendon Laboratory, Oxford. The AB Millimetre millimetre-wave vector network analyser (MVNA) in Oxford was used to develop a variety of novel resonant cavities in order to study the high-frequency conductivity of organic molecular metals and other solids. The cavities were used with the Clarendon Laboratory's high-field magnets (up to 18 T) to study a variety of magnetic resonance phenomena in organic molecular metals and Heisenberg antiferromagnets. The Oxford high-field magnets were used in magnetotransport studies of organic solids.
VSM, Leuven. The Leuven pulsed-field magnets were used to extend magnetotransport and magnetometry measurements initiated in Oxford and Moscow to magnetic fields of up to 70 T. Experiments were carried out on a variety of organic molecular metals.
General Physics Institute, Moscow. Cyclotron and spin resonance studies of single crystals of organic molecular metals were carried out at low temperatures, and over a wide frequency range. To this end, a magneto-optical spectrometer for fields of up to 7 T, based on backward-wave oscillators was constructed. To ensure tunability over the range 20-120 GHz, an original, non-resonant technique was specially adapted for use with the small, single-crystal samples. A large number of magnetotransport and thermoelectric power measurements were also carried out on organic metals. This entailed the development of installations for measurements of galvanomagnetic parameters and thermoelectric power at temperatures from 300 K to 1.5 K.
P.N.Lebedev Physical Institute, Moscow. Theoretical studies of the character of low-frequency excitations in systems of reduced dimensionality and their influence on the magnetic and magneto-optical responses of organic conductors close to density wave instabilities were undertaken. Investigations of the influence of Fermi liquid effects on the groundstates of organic conductors were performed. The calculations involved the use of memory function and mass operator techniques to estimate the groundstate many-body effects and effective mass renormalisation.
Landau Institute for Theoretical Physics, Moscow. Theoretical analysis of the influence of many-body effects and sample geometry/morphology on cyclotron resonance spectrum in organic metals was carried out using Green's funtion techniques. Calculations were made of the electron spin resonance line shapes in organic metals.
