Frontiers in Magnetic Materials

The book aims to provide comprehensive and practical guidance on magnetismand magnetic materials. It involves four parts, focusing on fundamentalmagnetism, hard magnetic materials, soft magnetic materials andother functional magnetic materials.Part I highlights the ubiquity of magnetism and the close relationshipsbetween magnetic materials and our daily life. Perspectives on magnetismfrom Engineering and Physics are provided to introduce the two unit systems,followed by the origin and categories of magnetisms. An introductionof important parameters during magnetization and magneticmeasurement techniques are then provided to lay a solid foundation forthe readers for better understandings of the design and development ofdifferent magnetic materials.Important magnetic materials are then introduced in the subsequentparts, 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 assoft magnetic materials such as Fe-based alloys, composites and ferritesare discussed. Other functional magnetic materials span a wide range,involving smart materials with magneto-X effects, together with magneticmaterials for applications including electromagnetic wave absorption,biomedicine and catalysis, etc. For these magnetic materials, more emphasisis placed on the latest advances and interdisciplinary perspectives.
