Abstract

Abstract: By using quantum Monte Carlo (MC) simulation, the electric properties of an Ising spin superlattice formed by two ferroelectric slabs A and B with an antiferroelectric interfacial coupling was studied within the framework of the Transverse Ising Model (TIM). We have examined the effects of the temperature T and the transverse field Ω on the polarization properties. We have also examined the effects of the interfacial coupling J AB, T, and Ω on the hysteresis behavior. Our results are in good agreement with the previous theoretical results; we have found that the critical temperature T c and the critical transverse field Ω c decrease with the increase of Ω and T respectively. In addition one or triple hysteresis loops can appear in the present system.
