The subject of electronic and ionic materials has grown rapidly over the last 20 to 30 years. The application of these materials has had a significant impact on modern industries and on society in general. The subject is so important that no electrical engineering, materials science and engineering, applied physics or chemistry degree would be complete without it.This valuable textbook is aimed at engineering and technology undergraduates who have a background in physics or chemistry only at first year level. It provides a basic understanding of the properties and uses of a wide range of electrically and ionically conducting materials. It is not intended to be a solid state physics or chemistry book, and so the mathematics is kept to a minimum. However, it is intended to give the student an overview of a wide range of electrical materials and their uses in today's society.

Presents an overview of various materials, such as conducting materials, semiconductors, magnetic materials, optical materials, dielectric materials, superconductors, thermoelectric materials and ionic materials. This title includes chapters on thin film electronic materials, organic electronic materials and nanostructured materials.

Revision of a classic reference on ferrite technology Includes fundamentals as well as applications Covers new areas such as nanoferrites, new high frequency power supply materials, magnetoresistive ferrites for magnetic recording

This concise book presents the basic concepts of magnetism and magnetic properties pertinent to permanent magnetic materials. Emphasis is placed on hexaferrite materials for permanent magnet applications, with M-type ferrites as the focal point. The relatively high metallicity of magnetic materials for practical applications imposes limitations for their efficient use. Accordingly, magnetic oxides with ferromagnetic properties emerged as the most widely used magnetic materials for practical applications, owing to their characteristic high resistivity and low eddy current losses, chemical stability, simplicity of production in mass quantities, and other favorable characteristics. An important class of these oxides is the class of hexagonal ferrites developed in the early 1950’s, which dominated the world market of permanent magnet applications since the end of the 1980’s. Among these ferrites, the magnetoplumbite (M-type) hexaferrite, is produced nowadays in large quantities at very competitive low prices, thus providing the permanent magnet market with probably the most cost-effective magnetic material.

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. - Provides background information regarding various basic magnetic phenomena and related theories, and defines the different natures of magnetic materials - Covers a wide range of hard and soft ferrites and related nanocomposites, particularly focusing on the correlation between structural features and magnetic analysis - Explores the role of substituted cations on the structural, thermal, magnetic, and microwave characteristics of ferrites and their nanocomposites - Discusses the mechanism involved for magnetic properties of major types of ferrite-ferroelectric magneto-electric components, exchange spring ferrite nanocomposites for fabricating next-generation permanent magnets, ferrite carbon nanocomposites for suppressing high-frequency electromagnetic radiation, and ferrite photocatalysts for omitting pollutants from our environment - Assesses the major challenges of experimental characterization and novel manufacturing techniques for fabrication of high quality ferrite, in terms of purity, shape, size, and distribution, and the application on an industrial scale
