多铁性磁电复合薄膜由于其表现出诸如磁电耦合效应、铁电场效应、交换偏置效应、隧穿电致电阻效应等十分丰富的物理现象以及在高灵敏度磁传感器、多态存储器、换能器等各种功能器件中具有潜在的广泛应用前景而受到国际上的关注。本文主要介绍了层状多铁性磁电复合薄膜材料研究现状、磁电复合薄膜中与界面相关的各种物理效应、基于高性能铁电单晶和钙钛矿锰氧化物薄膜的多铁性异质结中的应变效应与铁电场效应及其相互竞争等磁电耦合特性,并对多铁性磁电复合薄膜材料的发展趋势和应开展的研究提出几点建议。
Multiferroic magnetoelectric composite thin films have attracted great interest due to a variety of interesting physical phenomena such as the magnetoelectric coupling effect, ferroelectric field effect, exchange bias effect, tunneling electroresistance effect and their potential device applica- tions in high sensitive magnetic sensors, multistate memories, actuators etc.. In this paper, we briefly summarizes recent research progresses in the field of layered multiferroic magnetoelectric composite thin films that show a variety of interesting physical effects closely related to interface between the ferroelectric layer and the ferromagnetic layer. The strain effect, the ferroelectric field effect, and the competition between these two effects as well as magnetoelectric coupling in multiferroic heterostructures composed of perovskite manganite thin films grown on high perfor- mance ferroelectric single-crystal substrates are also briefly introduced. Finally, we propose a few suggestions for feature development of multiferroic magnetoelectric composite thin films.
