Size effects of ferroelectric particles described by the transverse Ising model

Abstract

The size effects of ferroelectric particles described by the transverse Ising model have been studied taking into account the long-range interactions. The size dependence of the mean polarization, Curie temperature, and the mean susceptibility, as well as the critical size of the particle, have been obtained. The profile of the polarization is given. The size effects of the ferroelectric particle show a strong dependence on the interaction range.
