Abstract
Lattice dynamics of displasive-type ferroelectrics with impurities is considered. Using the self-consistent phonon theory (SCPT) and the coherent potential approximation (CPA) the phonon spectrum of a disordered lattice is obtained and the dependences of Curie temperature and Curie-Weiss constant on the concentration×are calculated for 0 ≤ x ≤ 1.Keywords
