Antiferroelectric-Ferroelectric Switching in a Simple “Kittel” Antiferroelectric

抄録

The intrinsic switching path for the electric field enforced transition from antiferroelectric to ferroelectric states has been computed for the simple Kittel linear antiferroelectric. The generalized switching curves give values of the polarization, free energy, and dielectric susceptibility as a function of applied field for a number of different antiferroelectric stabilities. The switching curves are qualitatively similar to those in real perovskite antiferroelectrics, and the possible extension of the treatment to real materials is discussed.
