New Molecular Superconductor, β-[(CH3)4N][Pd(dmit)2]2

Abstract

Abstract High-pressure resistivity studies on [(CH3)4N][Pd(dmit)2]2 have revealed the system to be a new molecular superconductor. The superconducting transition has been observed above 6 kbar. The mid-point transition temperature T is 6.2 K at 6.5 kbar. The crystal has the structure almost isomorphous to the high-pressure superconductor, [(CH3)4N][Ni(dmit)2]2.
