在Landau唯象理论框架下，研究了厚度对1-3型多铁复合薄膜的准铁相变温度、自发极化、磁化强度和磁滞回线的影响。我们考虑了电致伸缩和磁致伸缩效应，以及铁电/铁磁部分和薄膜/衬底界面产生的失配应变。并对外场作用下的蝶环进行了模拟。
The effect of thickness on the para–ferro-phase transition temperatures, the spontaneous polarization and magnetization and hysteresis loops of 1–3 type multiferroic composite thin films was studied in the framework of Landau phenomenological theory. We took into account the electrostrictive and magnetostrictive effects, misfit strains induced from the interfaces of ferroelectric/ferromagnetic portions and film/substrate. Butterfly loops under external fields were also simulated.
