论文摘要
由Sol-Gel Techniques制备了具有组合物（1-X）BATI0.8SN0.2O3 - （x）LA0.5CA0.5CA0.5MNO3（x = 0，0.3，0.5，0.7，0.9和1）的多效复合材料。具有0-3和3-0型连接的复合材料的rietveld改进表现出纯相的形成，并确认了复合样品的分数。发现复合材料晶粒尺寸随着LA0.5CA0.5MNO3含量的增加而略有下降。复合陶瓷的磁性测量结果逐渐增加，随着LA0.5CA0.5CA0.5MNO3含量的增加，饱和度逐渐增加。介电数据表明，与母体化合物BATI0.8SN0.2O3（BTSO）相比，复合材料显示出介电常数的高值。此外，尝试测量磁电耦合系数，并在一定的频率和温度条件下解释这些材料中发生的负介电常数和损失。
Multiferroic composites with the composition (1-x) BaTi0.8Sn0.2O3 - (x) La0.5Ca0.5MnO3 (x =0, 0.3, 0.5, 0.7, 0.9 and 1) were prepared by sol-gel techniques. Rietveld refinements of the composites with 0-3 and 3-0 type connectivities exhibit the formation of pure phases and confirm the fraction of the composite samples. It was found that the composites grain size decreases slightly with increasing the La0.5Ca0.5MnO3 content. Magnetic measurements of the composite ceramics exhibit a gradual increase in saturation and remanent magnetization with increasing La0.5Ca0.5MnO3 content. Dielectric data demonstrate that the composite materials show high values of the dielectric constant in comparison with the parent compound BaTi0.8Sn0.2O3 (BTSO). In addition, an attempt is made to measure the magnetoelectric coupling coefficient and to explain the negative permittivity and losses occurring in these materials at a certain frequency and temperature conditions.
