弛豫多铁性材料研究进展
Progress of Relaxor Multiferroic Materials
摘要
Abstract
The multiferroic material, which shows the coexistences of multi ferroic orders (ferroelectricity, ferro-magnetism or ferroelasticity), can realize the mutual control of the electric and magnetic signals, and becomes one of the hottest research topics. The long-range ferroelectric or ferromagnetic order may be broken in compositionally disordered systems. In this situation, it is posssible that materials display relaxor behavior. Multiferroic materials pos-sessiong at least one ferroic relaxor character can be named as relaxor multiferroics. The polarization (or magnetiza-tion) is very sensitive to the applied electric field (or magnetic field). Besides, the magnetoelectric coupling effect of relaxor multiferroics is different from that of multiferroics with long ferroic orders. In this paper, the most recent and important theoretical and experimental advances in this new research field are reviewed. Firstly, basic physical con-cepts of the relaxor ferroic orders and the different mechanism of the magnetoelectric coupling effect on materials are introduced with the coexistence of relaxor ferroelectric ordering and relaxor magnetic ordering. Then, the recent re-searches on two sorts of the relaxor multiferroics, including perovskite (PbB1B2O3based and BiFeO3based) and non-perovskite (Bi-layered based and improperly ferroelectric based) structural materials, are reviewed. Finally, the further development of relaxor multiferroics is prospected.关键词
