Synthesis, Characterizations, and Magnetic Properties of Mixed Spinel Mg1-xZnxFe2O4 Ferrites

Abstract

Mixed spinel Mg1-xZnxFe2O4 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 Mg1-xZnxFe2O4 ferrite expect x=0.2. All the mixed spinel Mg1-xZnxFe2O4 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.

Mixed Spinel Co0.4Zn0.6Fe2O4 Ferrite Nanoparticles As a Magnetic Photocatalyst: Synthesis and Dye Degradation

“…Ferrites are compounds of mixed oxides of iron and one or more other materials with ferromagnetic properties. Based on their crystal structures, ferrites can be categorized into three groups: spinel, garnet and hexagonal, each having its own importance [3,4]. When a photocatalyst is selected, The material's band gap determines the wavelength of light that it absorbs.…”
