This book focuses on the investigation of the basic properties of magnetic nanostructures, and the fundamental physics of novel nanostructures for submicron devices. It provides a broad overview of the latest developments in this emerging and fascinating field of nano-sized materials, with emphasis on the practical understanding and operation of devices using or based on nanostructured magnetic materials. The topics also include submicron technologies, nanoscale characterization, new techniques for the synthesis of nanoparticles as well as an in-depth treatment of their characterization and chemical and physical properties. Potential industrial applications of these advanced materials are also discussed.
