Abstract

Mixed spinel Mg_1-xZn_xFe₂O₄ ferrites (where x = 0, 0.2, 0.4, and 0.6) nanoparticles were synthesized by using microwave-assisted combustion route. As-synthesized powdered samples were checked by XRD analysis, field emission-scanning electron microscopy, and vibration sample magnetometer to investigate the structural, morphology, and magnetic properties, respectively. XRD results exhibited that the crystallite size increases with the decrease of Zn⁺² ion concentration for series of mixed spinel Mg_1-xZn_xFe₂O₄ ferrite expect x=0.2. All the mixed spinel Mg_1-xZn_xFe₂O₄ ferrite has different grain sizes with uniform distribution also presence voids in the samples. Pure magnesium ferrite has a lower net magnetization value but when magnesium ions (Mg⁺²) are replaced by zinc ions (Zn⁺²) then the value of saturation magnetization increases.
