摘要/Abstract

摘要： The transverse Ising model (TIM) in the effective-field theory based on the differential operator technique is developed to study the physical properties of a ferroelectric superlattice A3/B3 system. The effects of an external electric field on the polarization, susceptibility and pyroelectric coefficient of the ferroelectric superlattice A3/B3 system are discussed in detail. The susceptibility of the ferroelectric superlattice A3/B3 system decreases with the increasing of the electric field, implying that the polarization is weak.

关键词: Ferroelectric superlattice, Polarization, Pyroelectric coefficient, Susceptibility.
