Micromagnetics and Recording Materials

"Micromagnetics and Recording Materials" is a book that aims to provide a systematic theory of computational applied magnetism, based on Maxwell's equations of fields and Landau-Lifshitz equations of magnetic moments. The primary focus is on magnetic recording materials used in computer hard disk drives. Traditionally, "Micromagnetics" encompasses the areas of magnetization curve theory, domain theory, and analyses of read and write processes in recording systems. As part of the Springer Briefs series, this book covers the first two areas of micromagnetics. M-H loops of hard magnetic thin film media, soft magnetic layers, and tunneling magnetoresistive spin valves are examined based on the microstructures of thin films. Static domain structures and dynamic switching processes are analyzed in arbitrarily shaped magnetic devices, such as write head pole tips and magnetic force microscope tips.
