A New Organic Superconductor, λ-(BEDT-TSF)2GaCl4

Abstract
λ(BEDT-TSF)2GaCl4 has revealed to be a new organic superconductor, where BEDT-TSF is bis(ethylenedithio)tetraselena-fulvalene. The onset temperature of the superconducting transition was about 9.5 K and the mid-point transition temperature (Tc) was 8 K. The crystal belongs to triclinic system. BEDT-TSF molecules are arranged to form a “quasi-stacking structure,” where four molecules form a repeating unit.
