Introduction to Magnetic Materials

Introduction to Magnetic Materials, 2nd Edition covers the basics of magnetic quantities, magnetic devices, and materials used in practice. While retaining much of the original, this revision now covers SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and other up-to-date topics. In addition, the authors have added an entirely new chapter on information materials. The text presents materials at the practical rather than theoretical level, allowing for a physical, quantitative, measurement-based understanding of magnetism among readers, be they professional engineers or graduate-level students.

The Late B. D. Cullity was a group leader for the Manhattan Project in WWII, and then became professor of metallurgical engineering at Notre Dame University. He is best known for two widely used textbooks, Elements of X-Ray Diffraction and this book, Introduction to Magnetic Materials. His major research interests were in the use of x-ray diffraction to measure lattice strains and in magnetostrictive phenomena.

C. D. Graham worked at the General Electric Research Laboratory for fifteen years before moving in 1969 to the Department of Materials Science and Engineering at the University of Pennsylvania. He has published works on magnetic domain structure, anisotropy, thin films, permanent magnets, amorphous alloys, and magnetic measurements, plus several book chapters and three encyclopedia articles.
