摘要：

H-1-NMR, EPR and static magnetic susceptibility measurements have been performed on an organic conductor, theta-(BEDT-TTF)(2)CsZn(SCN)(4). The H-1-NMR-T-1(-1) and tie spin susceptibility exhibit anomalous enhancements at low temperatures. Around 20 K. where the spill susceptibility shows a minimum, the principal axes of the EPR g-tensor changed their directions, keeping the principal values constant. It indicates a possible change of the electronic nature. The low-temperature electronic state is discussed.
