多晶BaCoO 3 (BCO)钙钛矿氧化物的结构特征和磁性能都得到了深入研究。采用溶剂热法合成了多晶BaCoO 3陶瓷。通过使用热重分析,BaCoO 3的热稳定性(TGA)已检查。为了检查BCO陶瓷的晶体结构、显微结构和表面化学状态性质,进行了X射线衍射(XRD)、扫描电子显微镜(SEM)和X射线光电子能谱(XPS)实验。XRD 图表明,煅烧样品中存在的相是六方钙钛矿相。多层镀层结构可以在 SEM 照片中看到,并且 EDAX 证实了元素化学计量。在室温(RT)下对该化合物进行了等温磁化研究,发现该配合物具有铁磁性能。变形CoO 6拉曼和 XPS 发现的这一现象可能与称为钙钛矿的氧缺陷有关。这种错误的特性表明 BCO 纳米颗粒具有铁磁特性。

Investigation on structural, morphological and magnetic properties of Barium Cobaltite (BaCoO3) nanoparticle
Both the structural characteristics and the magnetic property of the polycrystalline BaCoO3(BCO) perovskite oxide have been thoroughly researched. The synthesis of polycrystalline BaCoO3 ceramics was accomplished using a solvothermal method. Through the use of thermogravimetric analysis, the thermal stability of BaCoO3 (TGA) was checked. In order to examine the crystal structures, microstructures, and surface chemical state properties of BCO ceramics, X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) experiments were carried out. The XRD patterns indicate that the phases that were present in the calcined samples were hexagonal perovskite phases. The multilayer plated structure can be seen in SEM picturesand EDAX confirmed the elemental stoichiometry. Isothermal magnetization studies on the compound were carried out at room temperature (RT), and it was discovered that the complex possessed ferromagnetic properties. The deformed CoO6 that was found by Raman and XPS may be related to the oxygen defect known as perovskite. This faulty property suggests that BCO NPs have a ferromagnetic character.
