Abstract

Ce-substituted BaFe₁₂O₁₉ (BaCe_xFe_12−xO₁₉, x = 0, 0.01, 0.03, 0.05) was prepared by citrate sol–gel method. The thermal decomposition process of precursor was investigated by TG-DSC. The phase composition of the BaCe_xFe_12−xO₁₉ was characterized by X-ray powder diffraction analysis (XRD) which reveals that the BaCe_xFe_12−xO₁₉ crystallizes in a hexagonal structure. The lattice parameter of BaCe_xFe_12−xO₁₉ increases slightly when Ce was substituted into BaFe₁₂O₁₉. The average crystallite size calculated from the XRD line broadening is about 30–33 nm and no intermediate phases are detected in the XRD patterns. The transmission electron microscope (TEM) analysis indicates that the particles of samples obtained are the rod-like morphology.
