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