## Abstract A microscopic theory of lattice dynamics of the ionic crystals is developed in the selfβconsistent HartreeβFock approximation. The work is based on a splitting of the dynamical matrix into two parts, a rigid ion and a polarization part. For ionic crystals such a splitting is especially
## Abstract In the framework of a microscopic model general expressions for the components of the gyration and electrogyration tensors for dielectric crystals are obtained. The lattice contributions to the effects and contributions from single ions (or ionic complexes) are separated. The temperatur
