Impact of Magnesium on Structural and Morphological Study of Co-Zn Ferrites

The Co0.8-xMgxZn0.2Fe2O4 (x = 0.00 to 0.56) ferrites were prepared by solid state reaction route. The phase composition and morphology of the synthesized ferrites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. From the XRD results, single phase cubic spinal structure with space group Fd-3m was confirmed. The lattice constant (a), particle size (D), hopping lengths (L-A and L-B), bond lengths (A-O and B-O), ionic radii (r(A) and r(B)), microstrain (epsilon,) and dislocation density (rho(D)) were reported. The lattice constant increased as magnesium additive increased. The SEM image affirmed size and shape of particles. Crystallite size and microstrain were realized by W-H plot and SSP.
