Magnetostatic Waves in Inhomogeneous Fields


Book Description

Magnetostatic waves (MSWs) in magnetodielectric media are fundamental for the creation of various highly efficient devices for analog information processing in the microwave range. These devices include various filters, delay lines, phase shifters, frequency converters, nonreciprocal and nonlinear devices, and others. Magnetostatic Waves in Inhomogeneous Fields examines magnetostatic waves and their distribution in non-uniformly magnetized films and structures. The propagation of magnetostatic waves in magnetodielectric environments is accompanied by numerous and very diverse physical effects, sharply distinguishing them from ordinary electromagnetic waves in isotropic media. The authors address dispersion properties and noncollinearity of phase and group velocity vectors, as well as non-reciprocal propagation. Key Features Offers mathematical tools used in the calculation of properties of magnetostatic waves Includes a current literature review of magnetostatic waves and domain structures in garnet–ferrite films Considers the issue of converting magnetostatic waves into electromagnetic ones

Ferromagnetic Resonance in Orientational Transition Conditions


Book Description

The unique properties of ferromagnetic resonance (FMR) in magnetodielectric solids are widely used to create highly efficient analog information processing devices in the microwave range. Such devices include filters, delay lines, phase shifters, non-reciprocal and non-linear devices, and others. This book examines magnetic resonance and ferromagnetic resonance under a wide variety of conditions to study physical properties of magnetodielectric materials. The authors explore the properties in various mediums that significantly complicate magnetic resonance and provide a summary of related advances obtained during the last two decades. It also covers the emergence of new branches of the spectrum and anomalous dependencies on the magnetic field. Key Features: Reviews basic principles of the science of crystallographic symmetry and anisotropic solid-state properties Addresses the inhomogeneous nature of the distribution of the magnetization in the material being studied Explains the mathematic methods used in the calculation of anisotropic solids of a solid Provides the reader with a path to substitute electromagnetic waves when magnetostatic apparatus prove insufficient




Spin Waves


Book Description

This book begins by introducing magnetism and discusses magnetic properties of materials, magnetic moments of atoms and ions, and the elements important to magnetism. It covers magnetic susceptibilities and electromagnetic waves in anisotropic dispersive media among other topics. There are problems at the end of each chapter, many of which serve to expand or explain the material in the text. The bibliographies for each chapter give an entry to the research literature.




Nuclear Science Abstracts


Book Description

NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.




Magnetostatic Surface Waves in Ferrimagnets Above 4 GHz


Book Description

Microwave properties of magnetostatic surface waves in saturated ferrimagnets are described. Particular emphasis is given to experimental aspects of the subject. A summary background is given of pertinent experimental investigations of magnetostatic surface waves (MSSW) from 1968, when they were first observed, to the present. Certain features such as nonreciprocity, electronic tunability, and high coupling efficiencies are discussed. Propagation losses, between 4 and 15 GHz, on chemically-polished yttrium iron garnet (YIG) slabs were measured. Effects of inhomogeneous internal fields, the effects of placing metal conducting planes parallel to the surface upon which the waves propagate to modify the dispersion relation, and the effects of surrounding a single crystal slab (supporting resonant modes) with metal coated polycrystalline YIG to increase field homogeneity, are considered. Magnetostatic surface wave losses, above a few GHz, are less than those of acoustic surface waves. It is concluded that MSSW technology complements ASW technology at high frequencies.

Crystals for Magnetic Applications


Book Description

Springer-Verlag, Berlin Heidelberg, in conjunction with Springer-Verlag New York, is pleased to announce a new series: CRYSTALS Growth, Properties, and Applications The series will present critical reviews of recent developments in the field of crystal growth, properties, and applications. A substantial portion of the new series will be devoted to the theory, mechanisms, and techniques of crystal growth. Occasionally, clear, concise, complete, and tested instructions fqr growing crystals will be published, particularly in the case of methods and procedures that promise to have general applicability. Responding· to the ever-increasing need for crystal substances in research and industry, appropriate space will be devoted to methods of crystal characterization and analysis in the broadest sense, even though reproducible results may be expected only when structures, microstructures, and composition are really known. Relations among procedures, properties, and the morphology of crystals will also be treated with reference to specific aspects of their practical application. In this way, the series will bridge the gaps between the needs of research and industry, the pos sibilities and limitations of crystal growth, and the properties of crystals. Reports on the broad spectrum of new applications - in electronics, laser tech nology, and nonlinear optics, to name only a few - will be of interest not only to industry and technology, but to wider areas of applied physics as well and to solid state physics in particular. In response to the growing interest in and importance of organic crystals and polymers, they will also be treated.
