Nickel Spinel Ferrites: A review

Spinel ferrite is a class of magnetic materials which derives this name due to its similarity with the naturally occurring MgAl2O4 mineral. Also known by the name of 'cubic ferrites', these ferrites have been the center of attraction for material scientists ever since their discovery. Among these spinel ferrites, nickel ferrites have become one of the best options for usage in different applications such as medical treatment, electronic devices, electromagnetic wave absorption materials and water purification. The popularity of these ferrites is due to their favourable properties such as high permeability, high resistivity and high saturation magnetization. The purpose of writing this review paper is to summarize the major researches in the field of nickel ferrites on one platform. The major research findings are tabulated and briefly summarized. The review paper is divided into four major sections. The first section, Introduction to spinel ferrites, presents different types of magnetic behaviors, the classification of ferrites, and a brief introduction to spinel ferrites and their structures. The second section, Nickel spinel ferrites, briefly describes nickel spinel ferrites, their possible applications, and different methods of their synthesis. The third section, named as Different dopings in nickel spinel ferrites, outlines the major research attempts in the field of nickel ferrites and their derivatives. The final and fourth section, Different properties of nickel ferrites, summarizes the major properties of nickel ferrites, which have been commonly studied.
