Abstract

Ferroelectric phase transitions and thermodynamic properties of disordered PbSc1/2Ta1/2O3 and PbSc1/2Nb1/2O3 solid solutions have been investigated by the Monte Carlo method. The parameters of the effective Hamiltonian were calculated within the generalized Gordon-Kim model. The obtained values of the phase-transition temperatures and spontaneous polarization are in satisfactory agreement with the experimental data.
