Description

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.

Index.

The revision will focus largely on making the book current in regards to its applications, measurement techniques, and system of units. There is a new chapter on information materials: digital recording technology and materials, magnetic memory, etc.This revision includes coverage of SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and all other changes necessary to bring it up-to-date.
"However, if you are a student learning about magnetism or are in industry or academia and need to learn about the fundamentals of magnetism, this is the book to own." (IEEE Electrical Insulation Magazine, 1 July 2011)
Offers a phenomenological approach to magnetic materials with an emphasis on materials, experimental methods, and applications.
* Great appeal to those working in the real world with magnetic materials.
* New chapter on information materials: digital recording technology and materials, magnetic memory, etc.
* While retaining as much of the original presentation as possible, this revision includes coverage of SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and all other changes necessary to bring it up-to-date.
