Abstract

A phenomenological theory is proposed for the solid solution systems between the ferroelectric Pb(Fe_2/3W_1/3)O₃and the antiferroelectric Pb(M_1/2W_1/2)O₃(M=Mn, Co, Ni), using Kittel’s free energy expression for the two-inflattice model. The expansion coefficients of the free energy were determined from experimental information about the phase diagrams and showed a systematic change with the component M. Good agreement was obtained between experimental data and calculated values.
