Li7diffusion constant in the superionic conductorLi3N measured by NMR

The anisotropic diffusion coefficient of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ in ${\mathrm{Li}}_3$N has been measured by the pulsed magnetic-field-gradient method of NMR. Activation energy and jump rates obtained for diffusion along the hexagonal $c$ axis are in good agreement with our previous data, thus suggesting that the hopping of Li ions between the inequivalent Li(1) and Li(2) sites dominates the conductivity along the $c$ axis.
