摘要

NMR experiments are reported for the copper chalcogenide spinel CuV_2S_4, which has incommensurate lattice distortions at low temperatures in spite of the cubic symmetry at high temperature. A broad spin-echo spectrum of ~(51)V has been observed below 90 K at 17 MHz, but it shows a remarkable frequency dependence where it becomes sharper with decreasing frequency. Possible coexistence of charge and spin density waves is suggested at low temperatures in this material.
