Ferrites belong to the wonder class of materials which are known for their wide application range. Among ferrites, spinel ferrites belong to the most promising soft magnetic materials with excellent properties like engineered band gap, high saturation magnetization, coercivity, and better thermal and electrical properties. Among spinel ferrites, Nickel ferrites: a soft, highly magnetic material that exhibit excellent electrical, magnetic, and optical characteristics. Nickel ferrites find their space in a variety of applications because of their unique properties when compared to other ferrite family members. These properties include high saturation magnetisation, less coercivity, high resistivity and permeability. In addition, nanometric Ni ferrites are unique in several properties with modified applications, such as high frequency applications, electronic devices with low loss, biomedical applications, and environmental remedial applications also. This review aim to explore possible synthesis routes, unique properties and diverse applications of Ni ferrite.
