A review of Z-type hexaferrite based magnetic nanomaterials: Structure, synthesis, properties, and potential applications

The vast range of uses that Z-type hexaferrite nanoparticles (ZTHNPs) offer in a variety of fields, including antennas, microwave absorption, and biomedicine has sparked a lot of scientific interest in these nanoparticles. Z-type hexaferrite possesses a soft magnetic character, planar magneto-crystalline anisotropy, and acceptable ultra-high frequency electromagnetic characteristics. The major topics of this review paper are the crystal structure, synthesis strategies (sol-gel, co-precipitation, solid-state reaction, hydrothermal techniques), characteristics, and prospective uses of Z-type hexaferrite, with a special emphasis on recently published research. Firstly, the crystal structure and most prominent synthesis strategies of ZTHNPs, with their benefits and drawbacks, are described. Secondly, we focused more of our attention on the magnetic, structural, and electromagnetic behaviours of this material. The final section discusses the prospective applications of these novel multifunctional materials.
