Manganese Zinc Ferrites having equimolar composition were synthesized through solution route. These were then doped with samarium in varying composition (x = 0, 0.1, 0.2). The prepared material was subjected to their structural, morphological and magnetization characterization. X-ray Diffractometer(XRD) results confirm cubic structure with lattice parameter which agrees well with the standard values reported in literature. The particle size, as calculated from Debye-Scherer’s formula, comes out to be 4-6 nm. Transmission Electron Microscopy (TEM) results show the particles to be of spherical morphology. The saturation magnetization (Ms) and coercivity (Hc) of the material was measured using vibrating sample magnetometer (VSM). The nature of the plots showsthe presence of super paramagnetic nature with zero remnant magnetization and coercivity. Fourier transform infrared (FTIR) spectra confirm the presence of all relevant functional group in the material. The results reported indicate that rare earth, Samarium, doping to these Mixed Ferrite is a noble way to improve the performance of soft ferrites.
