Abstract

There have been observed in a series of isostructural α-(BEDT-TTF)2MHg(XCN)4's a variety of ground states such as spin-density-wave metallic state (M=K, Tl, Rb; X=S), superconducting one (M=NH4; X=S), and simple metallic one (M=K, Tl ; X=Se). Current status of these researches is outlined, including the magnetic field effects on the first group which appear in high fields more than 20T at low temperatures.
