Abstract

The temperature dependence of the spin-lattice relaxation time T 1 and the 7Li NMR spectra of the Li0.7Nb3Se4 intercalation compound with one-dimensional channel structure have been studied. It is found that the temperature dependence of T 1 exhibits two relaxation minima, and the quadrupole splitting in the Li NMR spectra shows an anomalous temperature behavior. The inference is drawn that the observed effects are associated with the high-rate diffusive motion of lithium ions along one-dimensional channels and the interchannel transitions.
