Download or read book Micromagnetics and Recording Materials written by Dan Wei and published by Springer Science & Business Media. This book was released on 2012-04-28 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Micromagnetics and Recording Materials" is a book trying to give a systematic theory of computational applied magnetism, based on Maxwell equations of fields and Landau-Lifshitz equations of magnetic moments. The focused magnetic materials are magnetic recording materials utilized in computer hard disk drives. Traditionally, “Micromagnetics” includes the areas of “magnetization curve theory", “domain theory" and “read and write process analyses in recording systems”. As Springer Briefs, this book includes the first two areas of micromagnetics. M-H loops of hard magnetic thin film media, soft magnetic layers and Tunneling MagnetoResistive spin valves are solved based on the microstructures of thin films. Static domain structures and dynamic switching processes are analyzed in the arbitrary-shaped magnetic devices such as write head pole tips and magnetic force microscope tips. The book is intended for researchers who are interested in applied magnetism and magnetic recording in all disciples of physical science. Prof. Dan Wei works at Tsinghua University, China.
