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.
