Riassunto

Physics and Engineering Applications of Magnetism deals with one of the most important and fundamental research subjects in solid-state physics. For the first time a unified treatment of both the basic physics and the technological applications of magnetism is given. Among the topics discussed are: the generation and application of ultra-high magnetic fields; compound, amorphous, and thin-film magnetic materials; magneto-optic recording; and the imaging of magnetic domains.
