摘要：

Nuclear magnetic resonance (NMR) for Li-7 nuclei was performed in vanadium spinel, LiV2O4. An anomalous temperature dependence of the relaxation time T-1 was observed. Namely, the relaxation rate 1/T-1 first increases with increasing temperature and then decreases below about 50 K. Such an anomalous temperature dependence may reflect the critical behavior around the ferromagnetic instability predicted by the SCR theory.
