Abstract
A numerical simulation on the basis of a modified two-spin facilitated kinetic Ising model for the long-standing problem of the mixed mobile ion effect (or mixed alkali effect) in glasses is presented. The essential idea is an internal dynamical interaction between the cation motion and the dynamics of the cooperative regions of the glass. This interaction leads to a strong variation of the dc conductivity versus the composition ratio $f$ of the cations contained in the glass. Both the dependence on temperature and the dependence on the composition ratio can be obtained in good agreement with experimental measurements.
