摘要: The superconductivity of s-(BEDT-TTF)2trihalides is discussed based on the experimental results pressure effect resistivity and Fermi surface. We examine anion-alloyed how temperature dependence changes with pressure. find that distinctively classified between those exhibit do not. low superconducting samples decreases almost same rate as at room temperature, while non-superconducting does not change This also true recent 10 K-superconductor, κ-(BEDT-TTF)2Cu(NCS)2. Second topic this paper Shubnikov de Haas s-(BEDT-TTF)2I3 s-(BEDT-TTF)2IBr2. area surface are found to be 14 first Brillouin zone contrary expected value 12. discuss structure these materials other isostructural salts.
