Nanoscale Magnetic Materials and Applications covers exciting new developments in the field of advanced magnetic materials. Readers will find valuable reviews of the current experimental and theoretical work on novel magnetic structures, nanocomposite magnets, spintronic materials, domain structure and domain-wall motion, in addition to nanoparticles and patterned magnetic recording media. Cutting-edge applications in the field are described by leading experts from academic and industrial communities. These include new devices based on domain wall motion, magnetic sensors derived from both giant and tunneling magnetoresistance, thin film devices in micro-electromechanical systems, and nanoparticle applications in biomedicine. In addition to providing an introduction to the advances in magnetic materials and applications at the nanoscale, this volume also presents emerging materials and phenomena, such as magnetocaloric and ferromagnetic shape memory materials, which motivate future development in this exciting field. Nanoscale Magnetic Materials and Applications also features a foreword written by Peter Grünberg, recipient of the 2007 Nobel Prize in Physics.

The first part of this state-of-the-art book conveys the fundamentals of magnetism for atoms and bulk-like solid-state systems, providing a basis for understanding new phenomena which exclusively occur in low-dimensional systems as the giant magneto resistance. This wide field is discussed in the second part. Suitable for graduate students in physical and materials sciences, the book includes numerous examples, exercises, and references.

A detailed presentation of the physics of the various hysteresis models that are currently used to explain the magnetization reversal process, including coherent and incoherent magnetization processes, micromagnetism and its application in thin films, multilayers, nanowires, particles and bulk magnets, domain wall pinning and domain wall dynamics, and Preisach modelling. Some of the faulty concepts and interpretations that still exist in the literature are rectified. Magnetic imaging techniques are reviewed, including TEM, SEM, magnetic force microscopy, and optical microscopy. Temperature, field and angular dependence of coercivity, magnetic interactions and magnetic phenomena are reviewed and their effect on magnetic hysteresis is discussed. The magnetic properties of novel materials are discussed, including nanoparticles, nanocrystalline granular solids, particulate media, thin films, and bulk magnets. Finally, present and future applications of novel materials are presented, including magnetic and magneto-optic recording media, magneto-electronics, sensors, magnetic circuit design, and novel structures created from rigid, high-energy permanent magnets.

This book reports recent mathematical developments in the Programme "Analysis, Modeling and Simulation of Multiscale Problems", which started as a German research initiative in 2006. Multiscale problems occur in many fields of science, such as microstructures in materials, sharp-interface models, many-particle systems and motions on different spatial and temporal scales in quantum mechanics or in molecular dynamics. The book presents current mathematical foundations of modeling, and proposes efficient numerical treatment.

Magnetic Ceramics describes the structure, preparation techniques, magnetic properties and applications of iron-based oxides also known as ferrites; metallic magnetic materials are also covered in depth. The main purpose of the book is to provide an up-to-date overview of the relevant aspects of ferrites, which cover a wide range of magnetic properties and applications such as high-frequency transformer cores, permanent magnet cements, microwave telecommunication devices, magnetic recording media and heads. The approach is that of materials science, characteristically interdisciplinary, where chemical aspects are covered in terms of synthesis/fabrication methods and crystal structures, and physics is introduced to provide a theoretical basis to magnetic properties. A special emphasis is given to the relationship between microstructure and properties.

A comprehensive overview, this book focuses on two directions of study: discovery of new effects that take place in magnetic wires and optimization of the magnetic, electrical, and mechanical properties of the wires, taking into account the technological application. The book presents the idea of moving to nanoscale, maintaining the achieved optimal parameters of microwires. While the focus remains on glass-covered wires of micrometer scale, it covers the first steps of the movement to "nano" range as an example of the versatility of the basic effects initially discovered for microscale.
