The book aims to provide comprehensive and practical guidance on magnetism and magnetic materials. It involves four parts, focusing on fundamental magnetism, hard magnetic materials, soft magnetic materials and other functional magnetic materials. Part I highlights the ubiquity of magnetism and the close relationships between magnetic materials and our daily life. Perspectives on magnetism from Engineering and Physics are provided to introduce the two unit systems, followed by the origin and categories of magnetisms. An introduction of important parameters during magnetization and magnetic measurement techniques are then provided to lay a solid foundation for the readers for better understandings of the design and development of different magnetic materials. Important magnetic materials are then introduced in the subsequent parts, delivering an overview of design principles, production technologies, research developments and real-world applications. For instance, rare-earth-free and rare-earth-based hard magnetic materials as well as soft magnetic materials such as Fe-based alloys, composites and ferrites are discussed. Other functional magnetic materials span a wide range, involving smart materials with magneto-X effects, together with magnetic materials for applications including electromagnetic wave absorption, biomedicine and catalysis, etc. For these magnetic materials, more emphasis is placed on the latest advances and interdisciplinary perspectives.

Over the past 25 years, there have been many advances in the understanding of magnetic phenomena in molecular systems. For example, a variety of low-dimensional materials, and many new ferromagnetic, antiferromagnetic, and ferrimagnetic systems have been synthesized and analyzed; metal cluster compounds that exhibit magnetic exchange have been examined; new orbital overlap theories have been proposed to explain magneto-structural correlations in exchange coupled systems; and efforts directed toward the preparation of an organic ferromagnetic material have produced new and interesting compounds. There have also been many advances in the use of magnetism as a probe of inorganic biomolecules.This volume brings together reviews of current research in magnetochemistry that are written by the world's leading researchers in the fields of chemistry, physics, materials science, and magnetism. It contains comprehensive and in-depth reviews that describe some of the current activities of these scientists and their research and lays the foundation for future research endeavors.

This book is a comprehensive treatment of fine particle magnetism and the magnetic properties of rocks. Starting from atomic magnetism and magneotistic principles, the authors explain why domains and micromagnetic structures form in ferrmagnetic crystals and how these lead to magnetic memory in the form of thermal, chemical and other remanent magnetizations. This book will be of value to graduate students and researchers in geophysics and geology, particularly in palemagnetism and rock magnetism, as well as physicists and electrical engineers interested in fine-particle magnetism and magnetic recording.

Magnetism and Structure in Functional Materials addresses three distinct but related topics: (i) magnetoelastic materials such as magnetic martensites and magnetic shape memory alloys, (ii) the magnetocaloric effect related to magnetostructural transitions, and (iii) colossal magnetoresistance (CMR) and related manganites. The goal is to identify common underlying principles in these classes of materials that are relevant for optimizing various functionalities. The emergence of apparently different magnetic/structural phenomena in disparate classes of materials clearly points to a need for common concepts in order to achieve a broader understanding of the interplay between magnetism and structure in this general class of new functional materials exhibiting ever more complex microstructure and function. The topic is interdisciplinary in nature and the contributors correspondingly include physicists, materials scientists and engineers. Likewise the book will appeal to scientists from all these areas.
