Abstract
We report angle-dependent magnetoresistance experiments on the charge- transfer salt alpha-ET2KHg(NCS)4 using fields of up to 30 T. The data indicate that the widely reported high-field 'kink' observed in the ma gnetoresistance of the alpha-ET2MHg(NCS)4 (M = K, Tl, Rb) family of ch arge-transfer salts represents a transition from an imperfectly nested spin-density wave ground state, characterized by a quasi-one-dimensio nal Fermi surface sheet tilted with respect to the bc plane, to a sta te with a cylindrical two-dimensional Fermi surface.
