项目摘要

We have investigated magnetic and dielectric properties and related microstructures in (1-x)BiFeO_3-xBaTiO_3 solid solution using a transmission electron microscopy (TEM), in combination with conventional magnetic and dielectric measurements. Nano-sized domain structures in the cubic phase of (1-x)BiFeO_3-xBaTiO_3 with 0.33<x<0.60 were found. From high-resolution TEM observation, it is revealed that the cubic phase in 0.33<x<0.60 is characterized as nano-scaled coexisting state of the polar rhombohedral structure and the non-polar cubic one, which should be regarded as the psudo-cubic phase. On the other hand, both P-E hysteresis measurements and the TEM experiments revealed that the cubic phase without any distortion due to the coexisting state appears in the x=0.60 compound at room temperature. Our experimental findings suggested that (1-x)BiFeO_3-xBaTiO_3 is a good candidate materials showing a gigantic magnetoelectric effect as a magnetoelectric relaxor.
我们使用透射电子显微镜(TEM)研究了(1-X)BifeO_3-XBATIO_3实心溶液中的磁性和介电性能以及相关的微观结构,并结合了常规的磁和介电测量。发现了(1-X)Bifeo_3-XBATIO_3的纳米尺寸域结构,发现了0.33 <x <0.60。从高分辨率的TEM观察中,可以发现,0.33 <x <0.60中的立方相被特征在于极性菱形结构的纳米尺度共存状态和非极性立方体的状态,应视为psudo-cubibic相。另一方面,P-E磁滞测量值和TEM实验都表明,由于共存状态而没有任何失真的立方相在室温下出现在X = 0.60化合物中。我们的实验发现表明(1-X)Bifeo_3-Xbatio_3是一种很好的候选材料,显示出巨大的磁电效应,作为磁电宽松。
