摘要：

The Fermi surfaces in the kappa-type organic superconductors have been studied using Shubnikov de Haas(SdH) and de Haas van Alphen(dHvA) effect. The systematic change in the superconducting transition temperature among the kappa-phase superconductors are discussed in relation to the contribution of anion layers to the transport properties. The dHvA effect in kappa-(BEDT-TTF)2Ag(CN)2H2O show a similar but characteristic quantum oscillation compared with that of kappa-(BEDT-TTF)2Cu(NCS)2. We could obtain no oscillation in kappa-(BEDT-TTF)2Cu[(NCN)2]Br which has the highest Tc so far observed at ambient pressure.
