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 magnetoresistance of the alpha -ET2MHg(NCS)4 (M=K, Tl, Rb) family of charge-transfer salts represents a transition from an imperfectly nested spin-density wave ground state, characterized by a quasi-one-dimensional Fermi surface sheet tilted with respect to the b*c plane, to a state with a cylindrical two-dimensional Fermi surface.Keywords
