Abstract :
The 1H-NMR measurements were carried out on the organic conductor, (BEDT-TTF)3CuBr4, where strong coupling between π and 3d electrons are expected. The 1H spin-lattice relaxation rate, T1−1, was large about 20 sec−1 and almost temperature independent above 60 K, indicating the effect of localized magnetic moments. Anomalies at the structural transition (60 K) was small. An antiferromagnetic transition was confirmed: The magnitude of the moment at Cu site was estimated as 0.6-0.7 μB. The moment at the Cu site was found to survive in the metallic state under pressure.
