Nanomagnetism: Fundamentals and Applications is a complete guide to the theory and practical applications of magnetism at the nanometer scale. It covers a wide range of potential applications including materials science, medicine, and the environment. A tutorial covers the special magnetic properties of nanoscale systems in various environments, from free clusters to nanostructured materials. Subsequent chapters focus on the current state of research in theory and experiment in specific areas, and also include applications of nanoscale systems to synthesizing high-performance materials.
