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

The Co_0.8–xMg_xZn_0.2Fe₂O₄ (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 (ε,) and dislocation density (ρ_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.
