摘要：

We have prepared single crystals of a novel BEDT-TTF salts, (ET)(4)Ln(NCS)(6). CH2Cl2, where ET is an abbreviation of BEDT-TTF, bis(ethylenedithio)tetrathiafulvalene and Ln is a heavy rare earth element, Ho, Er, Yb and Y. They are semiconductors below room temperature. From the crystal structure and the magnetism of the Y compound, it is concluded that the pi electrons form a low dimensional spin system, as a result of charge separation and Mott localization. Characteristics of the 4f electrons appears as remarkable anisotropy and temperature dependence of the magnetic susceptibility of the Hd, Er and Yb compounds.
