Abstract

High-temperature synthesis of the perovskite composite material i.e., 0.5(SmFeO₃)-0.5(Ba_0.5Sr_0.5TiO₃) or SFO-BST was proficiently developed through solid-state reaction technique. X-ray diffractometer was utilized to analyze the polycrystalline single stage, and Rietveld Refinement approved the development of the tetragonal phase (P4mm) in the crystalline material. The dielectric, impedance, conductivity and optical behavior of the synthesized specimen have been scrutinized. At room temperature and above, the sample shows a large dielectric constant and a small tangent loss, making it an appropriate material for microwave absorbers. The complex impedance analysis demonstrates the influences of the grain and the grain boundary. The material's efficacy to be used in a new multiferroic device is supported by its ferroelectric and ferromagnetic properties. Furthermore, the application in semiconductor photovoltaic cells is endorsed through the UV–VIS data analysis.

用于设备应用的 SFO-BST 包晶的结构、电学和多铁特性

通过固态反应技术，高温合成了包晶复合材料，即 0.5(SmFeO3)-0.5(Ba0.5Sr0.5TiO3)或 SFO-BST。利用 X 射线衍射仪分析了多晶单级，并通过 Rietveld Refinement 确定了晶体材料中四方相（P4mm）的发展。对合成试样的介电、阻抗、导电和光学行为进行了仔细研究。在室温及以上条件下，样品显示出较大的介电常数和较小的正切损耗，使其成为微波吸收器的合适材料。复阻抗分析表明了晶粒和晶界的影响。该材料的铁电性和铁磁性支持了它在新型多铁氧体器件中的应用。此外，紫外可见光数据分析也证明了该材料在半导体光伏电池中的应用。
