Abstract

• Rare earth, ytterbium doped Zinc ferrites: Zn (YbxFe1-x)2O4 with x=0.0000, 0.0125, 0.0250, 0.0375 and 0.0500 were prepared by the solid state method. Effect of Ytterbium doping on structural and magnetic properties of Zinc Ferrite is reported. The phase formation of the prepared samples was analyzed by X-ray diffraction. The appropriate variations in lattice parameters and cell volume confirmed the successful substitution of Fe3+ ions with Yb3+ ions at octahedral sites. The bulk density (Db) and X-ray density (Dx) were also significantly varied by increased Yb3+ contents. XRD analysis reveal pure spinel phase in all the samples, without traces of secondary phases. The magnetic measurements were performed by using a soft magnetic Hysteresis Graphs Meter (DX-2012SD). It was found that saturation magnetic induction and coercivity followed decreasing trend with substation of Fe3+ ions by Yb3+ ions.
