This book provides a comprehensive discussion of magnetism, magnetic materials and related applications. It covers the physics of magnetism, magnetic phenomena in materials, size and dimensionality effects and applications including information storage, spin electronics, and biomedicine. When I was asked to review the new book Fundamentals and Applications of Magnetic Materials, I was hesitant at first, since a number of similar textbooks already exist. However, this book caught my attention. What I like about this book is the steady solid level of quality throughout the chapters. A particular strength lies in the chapters close to Krishnan's own research interest, those addressing small magnetic particles, medical applications of magnetism and magnetic imaging. I can very strongly recommend this book as a reference for daily work in magnetism research and teaching.
