✦ Synopsis

The Fermi surfaces in the m-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 K-phase superconductors are discussed in relation to the contribution of anion layers to the transport properties.

The dHvA effect in ~ -(BEDT-TTF)gAg(CN)gHgO show a similar but characteristic quantum oscillation compared with that of K-(BEDT-TTF~2Cu(NC~)~. We could obtain no oscillation in K-(BEDT-TTF)2Cu[(NCN)2]Br which has the highest Tc so far observed at ambient pressure.
