Abstract

Dynamic properties of Coulomb lattice gas models obtained from Monte Carlo simulation are briefly summarized. The utility of such models in describing the relaxational behaviour of complex ionic systems is pointed out. New simulations of conductivity spectra and nuclear spin relaxation are presented for the counterion model, where ions are diffusing in the presence of long-range Coulomb fields due to randomly placed charge-compensating centers. The results are discussed in comparison with experiments on ion-conducting glasses.
