A Current Review on the Synthesis and Magnetic Properties of M-Type Hexaferrites Material

Abstract

After the discovery of hexagonal ferrites or hexaferrites, it has been become important materials commercially and technically to study which is still growing on. In this article, we have reviewed about the M-type hexaferrites including their structural, synthesis techniques and important magnetic properties. The role of experimental synthesizing techniques adopted for preparation of M-type hexaferrites on the various parameters studied in this review paper. The substitution of holonium in BaM ferrite reduces the value of coercivity but not saturation magnetization and ramanence and the cobalt-titanium substituted ferrites were the most important M-type ferrites in the field of application in microwave properties and magnetic field industry.
