【摘要】：多铁性材料的自旋、电荷、轨道、晶格等多重有序存在着复杂的相互作用,且对磁场、电场、光场、应变和温度等多种外界环境敏感,从而表现出一些新奇的物理现象,使其在存储器、传感器、微波等领域中有重要的应用价值。随着对单相多铁材料研究的深入,人们已从简单钙钛矿结构的多铁性研究转向复杂的层状类钙钛矿体系,其丰富而复杂的结构给人们提供了更广泛的设计和调控空间。介绍并分析了如Double-Perovskite(DP)、Ruddlesden-Popper(RP)、Aurivillius(AU)以及A_nB_nO_(3n+2)系列等层状类钙钛矿多铁性特征的研究进展。人们已发现Bi_2FeCrO_6等DP体系、(1 x)(Ca_ySr_(1 y))_(1.15)Tb_(1.85)Fe_2O_7 xCa_3Ti_2O_7等RP体系、Bi_4NdTi_3Fe_(1 x)Co_xO_(15_ Bi_3NdTi_2Fe_(1 x)Co_xO_(12 δ)等AU体系以及La_6(Ti_(0.67)Fe_(0.33))_6O_(20)层状材料等,均具有室温或近室温多铁性。最后提出了当前面临的问题和对未来的展望。
[Abstract]:The spins, charges, orbitals, lattices and so on of polyferromagnetic materials have complex interactions, and they are sensitive to the magnetic field, electric field, light field, strain and temperature, showing some novel physical phenomena, such as the magnetic field, the electric field, the light field, the strain and the temperature, and so on. It has important application value in memory, sensor, microwave and other fields. With the further study of single-phase multi-iron materials, people have changed from the study of simple perovskite structure to the complex layered perovskite-like system. The rich and complex structure provides people with more extensive design and control space. The research progress of layered perovskite-like perovskites such as Double-Perovskite (DP) Ruddlesden-Popper (RP) Aurivillius (AU) and A _ S _ nBnO _ (3n _ 2) series are introduced and analyzed. 浜轰滑宸插彂鐜癇i_2FeCrO_6绛塂P浣撶郴,(1 x)(Ca_ySr_(1 y))_(1.15)Tb_(1.85)Fe_2O_7 xCa_3Ti_2O_7绛塕P浣撶郴,Bi_4NdTi_3Fe_(1 x)Co_xO_(15_ Bi_3NdTi_2Fe_(1 x)Co_xO_(12 未)绛堿U浣撶郴浠ュ強La_6(Ti_(0.67)Fe_(0.33))_6O_(20)灞傜姸鏉愭枡绛，
