  • Abstract
    We have discussed the specific contribution to the indirect exchange interaction in III-V-cubic materials that is caused by virtual impurity level-valence band electron excitations. As the indirect exchange interaction is short-ranged, the mean-field theory is not valid and we use more adequate percolation picture of a phase transition
