Magnetic Properties in Ferroelectric Superlattices with Two Alternative Layers Described by a Transverse Spin-1/2 Ising Model
並列摘要
The critical temperature, magnetization, and subceptibility in ferroelectric superlattices with two alternative layers described by a transverse spin-1/2 Ising model are studied using the effective field theory with a probability distribution technique. We discuss an Lt layer superlattice of simple cubic symmetry with nearest-neighbor interactions. We derive the phase diagram, the magnetizations profiles, and the susceptibilities. In such superlattices, the critical temperature can shift to either a lower or higher temperature compared with the corresponding bulk value. The superlattice longitudinal susceptibility diverges at the superlattice critical temperature.
