Foreword -- Preface -- Acknowledgements -- Permanent magnets -- Soft materials for electrical engineering and low frequency electronics -- Soft materials for high frequency electronics -- Magnetostrictive materials -- Superconductivity -- Magnetic thin films and multilayers -- Principles of magnetic recording -- Ferrofluids -- Magnetic resonance imaging -- Magnetism of earth materials and geomagnetism -- Magnetism and the life sciences -- Practical magnetism and instrumentation -- Appendices -- General References -- Index by material -- Index by subject.This book treats permanent magnet (hard) materials, magnetically soft materials for low-frequency applications and for high-frequency electronics, magnetostrictive materials, superconductors, magnetic-thin films and multilayers, and ferrofluids. Chapters are dedicated to magnetic recording, the role of magnetism in magnetic resonance imaging (MRI), and instrumentation for magnetic measurements.   .
