Investigation on structural, morphological and magnetic properties of Barium Cobaltite (BaCoO3) nanoparticle

Abstract

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.
