Abstract :
We report low temperature electronic properties of a newly synthesized organic conductor (DMET)2CuCl2, consisting of stacks of DMET molecules constructing a quasi-one-dimensional Fermi surface. Superconductivity transition below 0.8 K is found, which is suppressed by a small magnetic field of 0.1 T. Under magnetic fields, successive step-like anomalies of magnetoresistance and plateau-like Hall resistance with sign reversals are found, indicating the occurrence of field-induced spin density wave (FISDW) transitions. The angular-dependent magnetoresistance and thermopower are measured in order to clarify the quasi-one-dimensional electronic structure.
