Abstract
Peculiarities of the dielectric properties of the compound PbMg 1/3 Nb2/3 O3(PMN) such as the relaxation character of the dielectric polarization, deviation of permeability from the Curie-Weiss law above the Curie temperature etc. have been discussed on the basis of the idea of a diffused phase transition. 1-6 A model has been proposed, in accordance with which the features of the dielectric properties PMN are explained by the relaxation of the polar regions surrounded with a non polar phase, with the number of relaxing regions dependent on temperature.Keywords
