Opis

"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.

O autorze

Prof. Dan Wei received her B.Sc. in physics from Peking University, China in 1988. She was a CUSPEA (China-US Physics Exchange Application, 1979- 1989) exchange student. In 1993, she completed her Ph.D. in physics at University of California at San Diego (UCSD), USA. From 1993 to 1996, she was a postdoctoral researcher in the Center for Magnetic Recording Research (CMRR) at UCSD. In November 1996, she became an Associate Professor with the Dept. of Materials Science and Engineering (DMSE), Tsinghua University, Beijing, China. In August 2000, she became a full Professor with DMSE, Tsinghua University. Her research focuses on the micromagnetic theory of magnetic materials and magnetic information storage systems. She was elected as a senior member of Chinese Association of Electronics in 2002, a senior member of IEEE in 2003 and an IEICE overseas member in 2007. She is the chair of IEEE Magnetic Society, Beijing Chapter (2011-2013).
