B. D. Cullity wrote Introduction to Magnetic Materials explicitly for beginners, at the level of senior undergraduates or first-year graduate students. His ability to write about complex technical topics in a clear, coherent manner made the book an instant classic, and it has remained a popular introduction to the subject for students and teachers alike. Now, more than three decades since its initial publication, Introduction to Magnetic Materials has been revised and updated in this eagerly awaited Second Edition. Introduction to Magnetic Materials, Second Edition retains much of the original content, while also including updated or new coverage of: * Magnetic units, with emu-cgs and SI units used throughout * Demagnetizing factors * Magnetic measurements, including the SQUID and the alternating gradient magnetometer * Magnetic force microscopy * Amorphous alloys * Rare-earth magnets * Magnetic materials in computers * Magnetic behavior of superconductors * Added material on domain wall structure and energy The material is presented at a practical level, allowing readers to develop a solid understanding of magnetic properties, quantities, and behavior. This timely new edition will be useful to students as well as engineers and scientists involved with magnetic phenomena, materials, and measurements. It crosses traditional disciplinary boundaries, covering topics in solid-state physics, materials science, electrical engineering, and computer science. It can serve as a basic learning and reference work for all those who need to understand the essentials of magnetic behavior.
