The purpose of the book is to provide an up-to-date overview of the relevant aspects of ferrites, which cover a wide range of magnetic properties and applications such as high-frequency transformer cores, permanent magnet cements, microwave telecommunication devices, magnetic recording media and heads. The author takes an interdisciplinary approach to describe the structure, preparation techniques, magnetic properties, and applications of iron-based oxides; metallic magnetic materials are also covered in depth.
