Book Description
MODERN FERRITES, Volume 1 A robust exploration of the basic principles of ferrimagnetics and their applications In Modern Ferrites Volume 1: Basic Principles, Processing and Properties, renowned researcher and educator Vincent G. Harris delivers a comprehensive overview of the basic principles and ferrimagnetic phenomena of modern ferrite materials. Volume 1 explores the fundamental properties of ferrite systems, including their structure, chemistry, and magnetism; the latest in processing methodologies; and the unique properties that result. The authors explore the processing, structure, and property relationships in ferrites as nanoparticles, thin and thick films, compacts, and crystals and how these relationships are key to realizing practical device applications laying the foundation for next generation technologies. This volume also includes: Comprehensive investigation of the historical and scientific significance of ferrites upon ancient and modern societies; Neel’s expanded theory of molecular field magnetism applied to ferrimagnetic oxides together with theoretic advances in density functional theory; Nonlinear excitations in ferrite systems and their potential for device technologies; Practical discussions of nanoparticle, thin, and thick film growth techniques; Ferrite-based electronic band-gap heterostructures and metamaterials. Perfect for RF engineers and magnetitians working in the field of RF electronics, radar, communications, and spintronics as well as other emerging technologies. Modern Ferrites will earn a place on the bookshelves of engineers and scientists interested in the ever-expanding technologies reliant upon ferrite materials and new processing methodologies. Modern Ferrites Volume 2: Emerging Technologies and Applications is also available (ISBN: 9781394156139).

Book Description
Subsidiary resonance phenomena in single-crystal ZnY and Mn-ZnY have been theoretically and experimentally investigated. Using a general expression for the first-order spin-wave instability, the threshold fields for pump frequencies above the characteristic frequency are calculated. Good agreement is shown between experimental data and theoretical predictions. (Author).

Book Description
A single text that incorporates all of the theoretical principles and practical aspects of planar transmission line devices - since the early development of striplines, it has been sought by countless microwave engineers, researchers, and students. With the publication of Networks and Devices Using Planar Transmission Lines, the search for that one authoritative resource is over. This is more than just a handbook, much more than a theoretical treatment. It's the ideal integration of the theory and applications of planar transmission lines and devices. Striplines, microstrips, slot lines, coplanar waveguides and strips, phase shifters, hybrids, and more - the author examines them all. For each type of structure, his treatment is complete and self-contained, including: Geometric characteristics Electric and magnetic field lines Solution techniques for the electromagnetic problem Quasi-static, coupled modes, and full wave analysis methods Design equations Attenuation Practical considerations Of particular interest is the author's comprehensive treatment of planar ferrimagnetic devices, such as phase shifters, isolators, and circulators, and three appendices dedicated to the theoretical aspects of ferrimagetism. Five other appendices provide thorough reviews of various theoretical concepts implicit in the body of the work, such as wave theory, the external properties of networks, and resonant circuits.

Book Description
The Use of Ferrites at Microwave Frequencies describes the applications of ferrites at microwave frequencies and the apparatus involved. Topics covered range from the properties of ferrites to gyromagnetic and non-reciprocal effects, ferrite isolators, circulators, and modulators. The use of ferrites in variable frequency filter cavities is also discussed. Mathematical explanations are reduced to the strict minimum and only the results of calculations are indicated. This book consists of seven chapters and opens with a review of the theory of magnetism, touching on subjects such as the BOHR magneton, diamagnetism and paramagnetism, ferromagnetism and antiferromagnetism, ferrimagnetism, and demagnetizing. The next chapter deals with the elementary theory of gyromagnetic effects and covers the kinetic moment theorem, precession of the spin moment, gyromagnetic resonance, complex permeability, and gyromagnetic effects in the atom. The reader is then introduced to ferrites and their properties; non-reciprocal effects and their applications; and ferrite isolators, circulators, and modulators. The final chapter describes the use of ferrites in the design of cavities whose resonant frequency is controlled by a magnetic field or filters with variable characteristics. This monograph is written primarily for microwave and electronics engineers.
