Physics and Engineering Applications of Magnetism


Book Description

This book was originally published in Japanese in honour of Professor S. Chikazumi on the occasion of his retirement from the University of Tokyo in March 1982. Physicists who had been supervised by him or had closely col laborated with him wrote articles on recent developments in magnetism and its engineering applications. In the preface of his excellent textbook Physics of Magnetism (Wiley, 1964), Professor Chikazumi says that recent research in magnetism deals with fundamental physical problems and, at the same time, with more secondary magnetic phenomena, as well as with engineering applications of magnetic materials to electromagnetic machines, permanent magnets and electronic computers, and that the purpose of his textbook is to give a general view of these magnetic phenomena, focusing its main interest at the center of such a broad field. Always keeping such a viewpoint in mind, Professor Chikazumi has contributed a great deal to both fundamental physics and applications of magnetism. This is described in Chap. 1 of this book. Many books have been published on both the physics and applications of magnetism. However, no single book has a viewpoint covering both of them. The recent development of high technology needs such a broad viewpoint for scientists and engineers since it is a product of both fundamental science and technology. Research in magnetism is based on the response which materials show to the application of magnetic fields.




Carbon Based Magnetism


Book Description

Carbon Based Magnetism is the most complete, detailed, and accurate guide on the magnetism of carbon, the main element of living creatures. Written by the leading experts in the field, the book provides a comprehensive review of relevant experimental data and theoretical concepts related to the magnetism of metal-free carbon systems. These systems include carbon based compounds, namely organic radical magnetic systems, and magnetic materials based on carbon structures. The aim is to advance the understanding of the fundamental properties of carbon. This volume discusses all major modern hypotheses on the physical nature of magnetic ordering in carbon systems. The first chapters deal with magnetic ordering mechanisms in p-electron systems as well as molecular magnets with spins residing only in p-orbitals. The following chapters explore the magnetic properties of pure carbon, with particular emphasis on nanosized carbon systems with closed boundary (fullerenes and nanotubes) and with open boundary (structures with edge-localized magnetic states). The remaining chapters focus on newer topics: experimental observation and theoretical models for magnetic ordering above room temperature in pure carbon. The book also includes twenty three review articles that summarize the most significant recent and ongoing exciting scientific developments and provide the explanation. It also highlights some problems that have yet to be solved and points out new avenues for research. This book will appeal to physicists, chemists and biologists. - The most complete, detailed, and accurate Guide in the magnetism of carbon - Dynamically written by the leading experts - Deals with recent scientific highlights - Gathers together chemists and physicists, theoreticians and experimentalists - Unified treatment rather than a series of individually authored papers - Description of genuine organic molecular ferromagnets - Unique description of new carbon materials with Curie temperatures well above ambient.




Magnetism


Book Description

This book deals with the basic phenomena that govern the magnetic properties of matter, with magnetic materials and with the applications of magnetism in science, technology and medicine. It is the collective work of twenty-one scientists, most of them from Laboratoire Louis Neel du CNRS in Grenoble, France. The original version, in French, was edited by Etienne du Trémolet de Lacheisserie, and published in 1999. The present version involves, beyond the translation, many corrections and complements.

Magnetism


Book Description

Magnetic phenomena and materials are everywhere. Our understanding of magnetic behavior, once thought to be mature, has enjoyed new impetus from contributions ranging from molecular chemistry, materials chemistry and sciences to solid state physics. New phenomena are explored that open promising perspectives for commercial applications in future - carrying out chemical reactions in magnetic fields is just one of those. The spectrum spans molecule-based - organic, (bio)inorganic, and hybrid - compounds, metallic materials as well as their oxides forming thin films, nanoparticles, wires etc. Reflecting contemporary knowledge, this open series of volumes provides a much-needed comprehensive overview of this growing interdisciplinary field. Topical reviews written by foremost scientists explain the trends and latest advances in a clear and detailed way. By maintaining the balance between theory and experiment, the book provides a guide for both advanced students and specialists to this research area.

A unique reference work, indispensable for everyone concerned with the phenomena of magnetism!




The Physical Principles of Rock Magnetism


Book Description

Developments in Solid Earth Geophysics 5: The Physical Principles of Rock Magnetism explores the physical principles of rock magnetism, with emphasis on the properties of finely divided magnetic materials. It discusses the origin and stability of rock magnetizations, the role of remanent magnetism in interpreting magnetic surveys, magnetic anisotropy as an indicator of rock fabric, and the relationship between piezomagnetic changes and seismic activity. Organized into 13 chapters, this volume discusses the properties of solids, magnetite and hematite grains, and rocks with magnetite grains. It also explains various theories and equations in studying rock magnetism. Different types of magnetization are discussed, including their occurrence, significance, and effects. Some of the types include depositional and chemical remanent and thermoremanent magnetization. In addition, this book explains the thermal activation and Piezomagnetic effects, as well as the reversals of remanent magnetism. This reference contains appendices with tables of relevant functions, such as Langevin Function. This book is a valuable source of information for physicists and geologists.

Amorphous Magnetism


Book Description

This book presents some of the methods used in the theory of amorphous magnetism, from a single standpoint that amorphous magnets have a topologically disordered structure of the type given by the dense random packing of hard spheres.The primary aim is to show systematically the present theoretical apparatus in a form which would allow the reader to use it in investigations of still unsolved problems. Even within these limits, the theory of amorphous magnetism is now a very large subject. This book is not designed to review all the developments in this rapidly developing area. It is primarily intended for the novice in this field, rather than the specialist.




Physics of Magnetism and Magnetic Materials


Book Description

In this book, the fundamentals of magnetism are treated, starting at an introductory level. The origin of magnetic moments, the response to an applied magnetic field, and the various interactions giving rise to different types of magnetic ordering in solids are presented and many examples are given. Crystalline-electric-field effects are treated at a level that is sufficient to provide the basic knowledge necessary in understanding the properties of materials in which these effects play a role. Itinerant-electron magnetism is presented on a similar basis. Particular attention has been given to magnetocrystalline magnetic anisotropy and the magnetocaloric effect. Also, the usual techniques for magnetic measurements are presented. About half of the book is devoted to magnetic materials and the properties that make them suitable for numerous applications. The state of the art is presented of permanent magnets, high-density recording materials, soft-magnetic materials, Invar alloys and magnetostrictive materials. Many references are given.
