Impact of Co+2 substitution by Mg+2 on The Structural, Morphological and Magnetic Properties of The Mixed Spinel Co-Zn Ferrite

This work's main purpose is to investigate the impact of Co+2 substitution by Mg+2 on the structural, morphological and magnetic properties of Co0.4Zn0.6Fe2O4 ferrite which synthesized by microwave-assisted combustion method. The structural, morphological and magnetic properties of the synthesized samples are investigated by X-ray diffraction field emission- scanning electron microscopy, and vibrating sample magnetometry. Phase impurity the formation of phase cubic spinel structure is confirmed with a crystilite size increased from 22.5048 nm to 22.5896 nm when Co2+ ions are replaced by Mg2+ ions. FE-SEM image exhibits reveals that the particles in nanoscale. There are agglomerated with porosity and very high surface energy. The magnetic mesurments showed that the saturation magnetization was found to decreace from (70.20emu/g to 58.36) with values of the coercivity (500 Oe to 250 Oe)when Co2+ ions are replaced by Mg2+ ions which means that the samples are a soft ferrites.
