In 1950s, after the discovery of hexagonal ferrites called as hexaferrites, there has been an increasing level of curiosity in hexaferrites and still, it is increasing exponentially. Commercially and technologically, hexaferrites belong to a category of important magnetic materials due to their utilization in various applications such as permanent magnets, recording media, storage devices, rod antennas, high frequency devices, microwave devices etc. There are six types of hexagonal ferrites as M-type, Z-type, Y-type, X-type, U-type and W-type respectively, out of which, the most worldwide manufactured hexagonal ferrite is Barium M-type hexagonal ferrite named as BaM [1]. All categories of hexaferrites shows ferrimagnetic behaviour as their magnetic nature is inherently related to their crystal structure. The current chapter focuses on the classification and structure of hexagonal ferrites. In this book chapter, firstly, we report the six categories of hexaferrites as M, Y, W, X, Z, W and then, we provide a detailed comprehensive review of two approaches called as spinel and S/R/T based model for reporting the structure of hexagonal ferrites respectively. After that, we reported a comprehensive structure of each hexaferrite. Lastly, the concluding remarks have been presented in the current chapter.

“…For the fabrication of nanoparticles, firstly stoichiometric amounts of starting precursors were taken in distilled water and stirred on magnetic stirrer with a hot plate until both the aqueous solutions become clear. Mixed both the aqueous solutions and set their pH~7 by adding few drops of ammonia solution [30]. For the making of gel, add stoichiometric amount of gel precursor called ethylene glycol.…”

The decreasing levels of consumable water on earth have been a serious issue and this issue makes the researchers and scientists develop new technologies for the purification of polluted water. Several reports have been carried on wastewater remediation by utilizing spinel ferrite-based nanoparticles and their composites. The spinel ferrites-based nanoparticles utilized for wastewater treatment was cost effective, chemically stable, easily retrieved and reusable. The present work addresses the various fabrication techniques for the preparation of spinel ferrite-based nanoparticles and their utilization for the removal of organic and inorganic pollutants through the adsorption paths.

“…The high coercivity of MCNF is mainly attributed to the high magnetic anisotropy of Co 2+ at the B site of octahedron and its spin-orbit coupling. In addition, there are many factors affecting coercivity, such as spin tilt and lattice distortion, which can lead to coercivity changes [42].…”

“…According to their structure, ferrite can be divided into spinel, garnet, perovskite and magnetic lead stone, etc. According to the application, it can be divided into hard magnetic, soft magnetic, permanent magnetic, moment magnetic and other types [13][14][15][16]. The methods of preparing ferrite nanometer magnetic materials include sol-gel method, chemical co-precipitation method, hydrothermal method, microwave-assisted method and high-temperature decomposition method, among them the sol-gel method is simpler and cheaper than other methods [17].…”
