Abstract
A unified model of ionic motion in glasses is presented which relates consistently the different quantities observed in nuclear-spin relaxat ion and electrical-conductivity relaxation due to thermally activated ionic diffusion. Corresponding experimental data obtained in a low-ion ic-conductivity fluorozirconate glass are shown to be in reasonable ag reement with the resent approach. Limitations of the model are pointed out and are discussed in view of observed deviations between the diff erent experimental results.
