Summary on Grant Application Form
Crystalline organic molecular metals form a very interesting system in which to study the effect of electron correlations. Although organic metals share many of the features of cuprate superconductors (quasi-two-dimensional bandstructure, proximity to antiferromagnetism, d-wave superconductivity etc.) and heavy-fermion systems (corrrelations, heavily renormalised effective masses), their bandstructure is inherently simple and may be readily measured. The interaction energy scales are such that laboratory magnetic fields (45 T steady, 100 T pulsed) can potentially access many exotic groundstates, including, as we have recently shown, phases such as the Fulde-Ferrell-Larkin-Ovchinnikov state and Frohlich superconductivity. We propose the implementation of improved MHz and GHz techniques which will allow (i) the sensitive detection of the phase boundaries between groundstates; (ii) the measurement of the evolution of phenomena such as cyclotron resonance and Fermi-surface traversal resonances with frequency; (iii) the study of phase-coherence effects and (iv) quantitative deductions of the intdayer conductivity. These will be compared with complementary measurements of the bandstructure using e.g. de Haas-van Alphen and angle-dependent magnetoresistance oscillations. The scientific aim of the project is to understand the prerequisites for the various low-temperature groundstates by studying their evolution (and that of the interactions that produce them) with magnetic field, temperature, underlying (normal-state) bandstructure, effective dimensionality and disorder.
