Magnetoresistance and magnetic breakdown in the quasi-two-dimensional conductors (BEDT-TTF)${}_2$MHg(SCN)${}_4$[M=K,Rb,Tl]

Abstract

The magnetic field dependence of the resistance of (BEDT-TTF)${}_2$MHg(SCN)${}_4$[M=K,Rb,Tl] in the density-wave phase is explained in terms of a simple model involving magnetic breakdown and a reconstructed Fermi surface. The theory is compared to measurements in pulsed magnetic fields up to 51 T. The value implied for the scattering time is consistent with independent determinations. The energy gap associated with the density-wave phase is deduced from the magnetic breakdown field. Our results have important implications for the phase diagram.
