Abstract: For several novel applications, the synthesis and characterization of nanoferrites are crucial. Their synthesis techniques have a significant impact on their electrical and magnetic characteristics, which are important in many applications. The resultant ferrites can have different characteristics depending on the process used, including sol-gel (SG), SG auto-combustion, self-combustion, co-precipitation, reverse micelle, micro-emulsion, glass crystallization, precursor, and hydrothermal procedures. The synthesis, characterization, and applications of mixed nanoferrites with the formula MFe2O4 are reviewed in this study. M can represent a variety of elements, including Cu, Fe, Mg, Mn, Ni, and others. Excellent magnetic characteristics, such as strong coercivity, high anisotropy, high Curie temperature, and mild saturation magnetization, are displayed by nano-sized ferrites. They also possess noteworthy mechanical qualities including considerable hardness and desired electrical qualities like high electrical resistance and minimal eddy current losses. According to our investigation, mixed nanoferrites show better qualities than single-component ferrites, which make them attractive options for a range of cutting-edge applications. This paper tries to give a comprehensive overview of the characteristics, synthesis methods, and possible uses of mixed nanoferrites, highlighting the latter are potential for major practical effect. We concentrate on the effects of these materials' form, size, and cation dispersion on their electrical and magnetic characteristics. Furthermore, we investigate the possible uses of mixed nanoferrites in a number of domains, such as: Superior magnetic and dielectric materials for electronics and sensors High-performance magnetic resonance imaging (MRI) contrast agents Biomedical uses, such as medication administration and the management of hyperthermia.
