Structural, Morphological, Spectroscopic, and Magnetic Properties of Mg-Zn Nanoferrite for High-frequency Applications

Mg-Zn spinel ferrite of nominal composition Mg0.4Zn0.6Fe2O4 was synthesized by cost-effective citrate precursor approach. The prepared nanoparticles were characterized by an “X-rays diffractometer, scanning electron microscopy, diffused reflectance spectroscopy, and vibrating sample magnetometer”. In the XRD pattern, the most intense reflection was observed from the (311) peak that corresponds to the cubic spinel phase of the produced ferrite. The average size of all crystallites was evaluated to be 38 nm. Uniformity in the size of the particles was detected with some agglomeration. The calculated energy band gap (1.88 eV) reveals the semiconducting nature of the prepared material. The low coercivity value (103 Oe) reveals that the synthesized material is a soft ferrite. The prepared sample of nanoferrite material was found to be suitable enough for high-frequency applications.
