Magnetic ceramics describes the structure, preparation techniques, magnetic properties and applications of iron-based oxides, also known as ferrites. The main purpose of the book is to provide an up-to-date overview of the relevant aspects of ferrites. These cover a wide range of magnetic properties and applications such as high-frequency transformer cores, permanent magnets, microwave telecommunication devices, magnetic recording tapes and heads. The subject is approached by emphasising its interdisciplinary nature. Synthesis and fabrication methods and crystal structures are covered alongside the theoretical basis of magnetic properties. This is a much needed book which fills a gap in the ceramics literature. It has been written to appeal to the international community of materials scientists, including researchers in industry and graduate students.
