摘要
多铁性材料是一种同时具有铁电、铁弹、铁磁等两种或者两种以上"铁性"的材料,可以通过多种序参量的耦合产生新的效应,在电子信息、传感、存储、无线网络等领域具备广阔的应用前景。当前在室温下具有强磁电耦合效应的多铁性材料仍然是学者们研究的重点,但基于多铁材料的器件还没有实现应用。应变工程是一种可以有效影响多铁材料物理性质的调控手段,通过晶格与电子、自旋、轨道等的相互作用来影响材料的电、磁、光、声等物理特性,因此通过应变调控多铁性薄膜结构和性能,受到了研究人员的广泛关注。本文通过调研多铁性材料中应变工程的研究,总结了应变调控手段及其对材料物理性能的影响,期望为多铁性材料的研究和发展提供研究思路。
The original definition of multiferroics is that one owns two or three “ferro” properties, such as ferroelectricity, ferroelasticity, and ferromagnetism. Furthermore, novel effects would be generated by the cross-coupling effect among various orders of multiferroic materials, and it has a broad application prospect in electronic information, sensing, storage, wireless network and other fields. At present, researchers are still focus on the multiferroic materials with strong magnetoelectric coupling effect at room temperature. However, the realization and application of devices based on multiferroics are still on the way. Strain engineering is an effective way that can influence the physical properties of multiferroic materials. The physical properties of materials such as electricity, magnetism, and photoacoustic could be influenced by strain engineering through the interaction of lattice with electrons, spins, and orbits. Tuning the structural and physical properties of ferroelectric thin films by strain has been paid extensive attention. Through investigating the research of strain engineering in multiferroic materials in this paper, herein, the strain engineering in multiferroics are summarized and effect of strain engineering on the physical properties of multiferroics is reviewed. It is prospected that the current work may provide research ideas for the investigation and development of multiferroic materials.
