摘要：

We present the results of a H-1 NMR study of the single-component molecular conductor, [Au(tmdt)(2)]. A steep increase in the NMR line width and a peak formation of the nuclear spin-lattice relaxation rate, I IT,, were observed at around 110 K. This behavior provides clear and microscopic evidences for a magnetic phase transition at considerably high temperature among organic conductors. The observed variation in I IT, with respect to temperature indicates the highly correlated nature of the metallic phase.
