Abstract:
The synthesis of nanocrystalline BaFe12-2xCoxTixO19 with variations of x (x = 0, 1, 2, and 3) have been investigated. The formation of polycrystalline samples that the cationic of Co2+ and Ti4+ in Co-Ti substituted Fe in BaFe12O19 ferrites structure were prepared by solid state reaction method. The crystal structure, microstructure, and magnetic properties were characterized using powder X-ray diffraction, scanning electron microscope (SEM) and permagraph meter, respectively. The results show that the nanocrystalline BaFe12-2xCoxTixO19 has single phase with polycrystalline structure, the grain size decrease by doping, the coercivity (Hc) and saturation magnetization (Ms) decrease with increasing Co-Ti substitutions.
