Abstract
Spin–lattice relaxation rates of 7Li have been measured for Li2O, Li2SiO3 and LiAlO2 with pulsed nuclear magnetic resonance. Relaxation due to cation diffusion is observed with quadrupole and dipole interactions. Cation jump frequencies in the extrinsic region with apparent activation energies of ca. 0.4 eV for Li2O, 0.81 eV for Li2SiO3 and 0.77 eV for LiAlO2 are obtained. These activation energies are in good agreement with those of ionic conductivities in the extrinsic region.Keywords
