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.
