Interplay between the orbital quantization and Pauli effect in a charge-density-wave organic conductor £

Abstract The interlayer magnetoresistance of the low-dimensional organic metal α-(BEDT-TTF) 2 KHg(SCN) 4 under pressure shows features which are likely associated with theoretically predicted field-induced charge-density-wave (FICDW) transitions. At ambient pressure, a magnetic field strongly tilted towards the conducting layers induces a series of hysteretic anomalies. We attribute these anomalies to a novel kind of FICDW originating from a superposition of the orbital quantization of the nesting vector and Pauli effect on the charge-density wave. © 2001 Elsevier Science.
