摘要：

AC electrical conductivity, sigma, and Li-7 nuclear spin relaxation in rotating frame have been studied in the glass series xLi2O: (1 - x)GeO2, where x = 0.002-0.25. The temperature dependence of spin lattice relaxation rate (1/T1-rho) scales linearly with sigma-T when compared at the same frequency (20 kHz). This demonstrates a direct correspondence between nuclear spin relaxation and electrical conductivity due to lithium diffusion in these glasses above room temperature.
