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.
我们用透射电子显微镜结合常规的磁测量和介电测量研究了(1-x)BiFeO_3-xBaTiO_3固溶体的磁性和介电性质以及相关的微结构。在(1-x)BiFeO_3-xBaTiO_3(0.33;x<;0.60)立方相中发现了纳米尺度的磁畴结构。高分辨电子显微镜观察表明,0.33<;x<;0.60的立方相为纳米尺度的极三方结构和非极性立方结构并存的状态,应视为准立方相。另一方面,P-E磁滞测量和透射电子显微镜实验表明,在室温下,x=0.60化合物中出现了立方相,没有因共存状态而引起的任何变形。我们的实验结果表明,(1-x)BiFeO_3-xBaTiO_3是一种表现出巨大磁电效应的磁电驰豫材料。
