ON THE THEORY OF FIRST-ORDER PHASE TRANSITION IN ORDER-DISORDER FERROELECTRICS

Based on the Hamiltonian of the Ising model in a transverse field, we have considered the four-spin interaction which is responsible for the first-order phase transition observed in order-disorder ferroelectrics. Using the method of the retarded Green’s function we have determined the relative polarization, the spin-wave energy, the transverse and longitudinal damping. They are numerically calculated and discussed for different temperature and tunneling frequency values in the cases of first- and second-order phase transitions.

First Order Phase

We present common 1D model of first order phase transition based on coupled solution of order parameters evolution and heat transfer equations. Such a model may be used for simulation of phase transitions in multiferroics or magnetostructural phase transitions, for example. First order phase transition process has been described by Landau-Khalatnikov-like equation with the thermodynamic potential of 2-3-4 and 2-4-6 types.
