Improved optical and magnetic properties of polycrystalline Z-type hexaferrites by co-precipitation method

Z-type hexaferrites (HF) with polycrystalline characteristics were elegantly synthesized by co-precipitation. XRD results confirmed the Z-type ferrite nanoparticles as belonging to the polycrystalline phase and with a particle size of 6 nm. The FTIR spectrum exhibits low- and high-frequency resonances, which correspond to tetrahedral and octahedral voids and a stabilized ferrite structure. Optical properties were determined by visible light absorption between 200 and 500 nm in the UV-Vis broad reflectance spectrum. FE-SEM micrograph showed spongy morphology and strongly aggregated ions. VSM exhibits ferrimagnetic magnetic properties and got higher coercivity. These special ferrite materials will undoubtedly be useful in microwave absorption, high-frequency, and magnetic recording media.
