Polarization properties of ferroelectric superlattice studied by Monte Carlo simulation

The polarization property of a ferroelectric superlattice formed from two a lternating materials was studied using Monte Carlo computer simulation. Our study has been developed in a framework of the transverse king model with nearest-neighbor interactions. Both the effect of the transverse field and interface coupling strength have been taken into consideration. In view of our results which is in good agreement with previous theoretical results, i t is concluded that the Curie temperature of the superlattice increases wit h the increase of the interface coupling strength J(AB) The remanent polari zation and saturation coercive force of the superlattice are also presented .
