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

The interlayer magnetoresistance of the low-dimensional organic metal alpha-(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.
