Abstract
Pr substituted barium hexaferrite, Ba1-xPrxFe12O19 with x = 0.00-0.20 were synthesized by Oxide One Pot Synthesis (OOPS) process. The phase composition of Ba1-xPrxFe12O19 were characterized by X-ray diffraction analysis (XRD). The phase morphology of the barium hexaferrite powder was studied by scanning electron microscope (SEM) and energy dispersive X-ray (EDX) spectroscopy confirmed that the Pr completely substituted into barium ferrite. The magnetic properties was investigated by vibrating sample magnetometry (VSM). It was found that saturation magnetisation and coercive field can be improved by the substitution of Ba with Pr in BaFe12O19 powder. The saturation magnetisation increased at first to the maximum of 50 emu g-1 (x = 0.15) and then decreased to the 34 emu g-1 (x = 0.20), while the coercive field increased remarkably with increasing Pr ions content.
