Low-temperature electronic phases of EDT-TTF based molecular conductors

Abstract

Magnetic investigation was carried out for low temperatures electronic phases in (EDT-TTF) 2 AuBr 2 , which undergoes an SDW transition at 16 k. In the SDW phase, we observed an abrupt change of 1 H-NMR absorption line around 6 K where the 1 H-NMR spin-lattice relaxation rate shows an anomalous second peak. The electronic phase is discussed by microscopic point of view.
