As a fast-emerging and growing class of magnetic materials, ferrites have generated an increasing amount of interest for providing specific magnetic properties through controlled mixture in composites. The study of magnetic ferrite nanocomposites requires a multidisciplinary approach, involving novel synthesis techniques and an understanding of solid-state physics, electronic engineering, and material science. Magnetic Ferrites and Related Nanocomposites covers recent trends of various types of ferrite nanocomposites and evaluating the mechanisms for interpreting static and dynamic magnetic properties. Sections cover the fundamentals of magnetism, introducing different kinds of ferrites, ferrite characterization techniques, magneto-electric ferrite nanocomposites, exchange spring ferrite nanocomposites, shielding effectiveness and microwave absorption characteristics of ferrite-carbon materials, photocatalytic application of ferrite nanocomposites, and novel synthesis techniques for fabricating ferrite in nanoparticles, bulks, thin films, and nanofiber configurations. This book is an important reference for scientists, researchers, graduate students, and practitioners active in this field in order to broaden their understanding of ferrite nanocomposites and their impact on modern technology.

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.
