Z-type hexaferrites with polycrystalline characteristics were synthesized using co-precipitation method. The XRD results confirmed the polycrystalline phase and 6 nm particle size of the Z-type ferrite nanoparticles. The FTIR spectrum showed resonances corresponding to tetrahedral and octahedral voids and a stabilized ferrite structure. These special ferrite materials exhibited ferrimagnetic properties and high coercivity, making them useful for microwave absorption, high-frequency applications, and magnetic recording media.
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.
