摘要：

Following the introduction of kappa-(ET)(2)X (X=Cu[N(CN)(2)]Cl, Cu[N(CN)(2)]Br, Cu(CN)[N(CN)(2)], Cu(NCS)(2)) providing high-T-c organic superconductors, the pressure phase diagram of kappa-(ET)(2)Cu[N(CN)(2)]Cl giving the highest T-c is described, as an epitome of dramatic interplay between electronic and magnetic phases in pi electron system. This demonstrates the significance of two-dimensionality, electron correlation and soft lattice. The topology of the Fermi surfaces of kappa-(ET)(2)X is discussed in relation to the magnetooscillatory phenomena such as Shubnikov-de Haas effect, angle-dependent magnetoresistance and thermomagnetic effects.
