Magnetic materials are important materials for high-tech areas and technological development, which are being classified not only based on their origin but also by the nature of processing, properties, functions, and applications. This book presents an overview of the different types of new magnetic materials and hybrid structures that exhibit different magnetic phenomena and interesting properties. The reported materials are studied theoretically and experimentally, which are the building blocks of all technological innovations. Topics such as magnetic levitation are given for industrial applications. The chapters of the book provide a key description of magnetic materials. This book is suitable for undergraduate and graduate students and professionals including engineers, scientists, researchers, technicians, and technology managers. This book gives an idea to readers for scientific innovation in this field.
