Two different compositions of ferrites namely Ni0.53Cu0.12Zn0.35Fe2O4 and Mg0.2Cu0.3Zn0.5Fe2O4 have been synthesized by co-precipitation method and sintered at 900 °C/5h. The prepared samples are analyzed for their structural, morphology, elemental composition and magnetic properties by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence and vibrating sample magnetometer respectively. Spinel phase, along with the hematite as an additional phase, in both samples is confirmed from the XRD characterizations results. Rietveld refinement method is employed to analyze the structural parameters of the samples. Density and saturation magnetization have found to be increased from that of undoped sample values. Homogeneous distributions of particles and well defined particle sizes are revealed from SEM studies of the samples. Maximum entropy method is employed to compute the numerical value of various sites interactions in ferrites and the findings are compared and analyzed with that of magnetic studies.
