Hysteresis loop of a ferroelectric bilayer with an antiferroelectric interfacial coupling

Abstract

The intrinsic hysteresis of a ferroelectric bilayer with an antiferroelectric interfacial coupling is studied within the framework of the Transverse Ising Model. We find it is possible to exit triple hysteresis loops once the parameters of the two slabs are selected appropriately. The effects of the thickness, the interfacial coupling constant and the temperature on the hysteresis of the bilayer are investigated. The quantum effect on the hysteresis is also examined; it is found that the quantum effect can result in the disappearance of the hysteresis.
