摘要:

本文报道了单组分分子导体[Au(tmdt)_{2}]的~ 1H NMR研究结果。在110 K附近观察到NMR谱线宽度的急剧增加和核自旋-晶格弛豫速率1/ T_{1}的峰值形成。这种行为为有机导体在相当高的温度下发生磁相变提供了清晰的微观证据。观察到的1/ T_{1}随温度的变化表明金属相的高度相关性。

英文摘要:

We present the results of a ^{1}H 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, 1/T_{1}, 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 1/T_{1} with respect to temperature indicates the highly correlated nature of the metallic phase.
