Applied Magnetism

The book deals with the theory, experiments and applications of the main topical areas of applied magnetism. These selected areas include the physics of magnetic recording, magnetic and magnetooptic recording devices, systems and media, magnetic fine particles, magnetic separation, domains and domain walls in soft magnetic materials, permanent magnets, magnetoresistance, thin film magnetooptics, and finally, microwave, optical and computational magnetics. The material is organised into ten self-contained chapters which together provide a comprehensive coverage of the subject of applied magnetism. The aim is to emphasize the connection between the fundamental theoretical concepts, key experiments and the important technological developments which have been achieved in this field up to the present time. Moreover, when and where possible, pointers to future trends are indicated which, together with the background material, will promote further advancement of research.
