Study the Effect of the Substitution of Ba with Pr in Barium Ferrite Powder on Magnetic Properties

Abstract:

Pr substituted barium hexaferrite, Ba_1-xPr_xFe₁₂O₁₉ with x = 0.00-0.20 were synthesized by Oxide One Pot Synthesis (OOPS) process. The phase composition of Ba_1-xPr_xFe₁₂O₁₉ 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.
