Oscillatory magnetoresistance in the charge-transfer salt beta "-(BEDT-TTF)2AuBr2 in magnetic fields up to 60 T: Evidence for field-induced Fermi-surface reconstruction.

Abstract:

Magnetoresistance measurements carried out in pulsed magnetic fields of up to 60 T and at temperatures down to 350 mK and angle-dependent magnetoresistance experiments performed in quasistatic fields have been used to establish that the charge-transfer salt β″-(BEDT-TTF)2AuBr2 undergoes a change in electronic structure at ∼10 T. We propose that this arises due to a field-induced transition between two different spin-density-wave states. Furthermore, at the highest magnetic fields, both the ba...
