Effect on structural and magnetic properties of Mg2+ substituted cobalt nano ferrite

Abstract

Nanoparticle-sized inverse spinel structured Cobalt ferrite materials doped with Mg2+ at lower concentrations have been synthesized using sol-gel auto combustion technique. Two-step annealing procedure has been employed to obtain a clear phase of the synthesized materials. Structural and phase formation have been studied using the thermo gravimetric analysis, powder X-ray diffraction and Fourier transform infrared spectroscopy. Powdered samples texture and morphology has been studied using scanning electron microscopy. Moreover, magnetic properties were studied by room temperature vibrating sample magnetometer. Lattice parameters and crystallite sizes in the range of 8.3702–8.3845 Å and 53.2–81.2 nm, respectively, have been calculated. Tuned magnetic parameters have also been obtained using VSM measurement.
