The Spinel ferrites are a type of material with the chemical formula MB2O4, where M and B are transition metal ions. These materials have a spinel structure, which is made up of a cubic array of oxygen ions, with metal ions inhabiting both A(tetrahedral) and B (octahedral) sites. Spinel ferrites are versatile materials with excellent electricaland magnetic properties. The properties of spinel depend on several factors, including the preparation method, grain size, and the substitution of metal ions. The structural, dielectric, and magnetic properties of these ferrites should be altered by introducing different dopants. The broad range of applications for spinel structures includes electromagnets, where increasing the grain size can decrease residual loss. This paper discusses how changes in the metal ion site preference and the effect of grain size can impact various properties of spinel ferrites.
