This book provides a comprehensive discussion of magnetism, magnetic materials, and related applications. The logical train of thought progresses, in four parts, from physics of magnetism (§1–5), magnetic phenomena in materials (§6–8), size and dimensionality effects (§9–10), and applications in physical (§11, §13, §14) and biomedical (§12) technologies. Beginning with a description of magnetic phenomena and measurements on a macroscopic scale, it is followed by discussions of intrinsic and phenomenological concepts of magnetism, such as electronic magnetic moments and classical, quantum, and band theories of magnetic behavior. It then covers ordered magnetic materials (emphasizing their structure-sensitive properties) and magnetic phenomena, including magnetic anisotropy, magnetostriction, and magnetic domain structures and dynamics. This is followed by a comprehensive description of imaging methods to resolve magnetic microstructures (domains) along with an introduction to micromagnetic modeling. Size (small particles) and dimensionality (surface and interfaces) effects—the underpinnings of nanoscience and nanotechnology that magnetism brings into sharp focus—are then explored in some detail. The hallmark of modern science is its inter-disciplinarity and hence, after covering the required background material to establish a solid foundation, the second half of the book discusses, with extensive bibliography, information technology, magnetoelectronics, and the future of biomedicine via recent developments in magnetism. Modern materials with tailored properties require careful synthetic and characterization strategies; the book also includes relevant details of the chemical synthesis of small particles and the physical deposition of ultrathin films. In addition, details of state-of-the-art characterization methods and summaries of representative families of magnetic materials, including tables of properties, where appropriate, are presented. Finally, CGS equivalents (to SI) are regularly inserted in the hope that if one is referring to works of a recent antiquity this feature would be useful.
