Abstract

In this paper we report the microstructure and magnetic properties of Ti2+-Mn4+ substituted barium hexaferrites with formula of BaFe12-2xTixMnxO19 (x=0.2, 0.4, 0.6 and 0.8) which prepared by solid state reaction process. The ions were obtained from TiO and MnO2 precursors and mechanically alloyed with BaCO3 and Fe2O3 precursors. X-ray diffraction patterns for sintered samples confirmed that the materials are consisted with single phase BHF. Cell volume and crystallite size was found increase with increasing x. The crystallite size for all samples is below 70 nm, but the morphology shown that the grains is around 200-400 nm, which concluded that each grain are polycrystalline. The saturation magnetization increases up to x =0.4 and decrease for higher x, while the coercivity remain decreases monotonically for all x. The results can be interpreted as the site preferential occupation of Ti2+ and Mn4+ ions at low level substitution.
