In the modern world, the life style of humans is greatly influenced by electronic gadgets. These electronic gadgets need semiconducting and magnetic materials. In particular, the magnetic materials which find applications in almost all such gadgets need to be researched and better understood. Magnetism has diverse applications, from simple “loadstone” to complex DNA sequencing. The aim of this book is to describe the synthesis and characterization of various nano ferrite materials used for memory applications. It is now well established that materials synthesized in nanometer scale have novel properties compared to their bulk counterparts. The distinct feature of the book is the construction of charge density diagrams of ferrites by using the maximum entropy method (MEM). It is analyzed how the charge density distribution in the ferrite unit cell affects charge related properties.

The Handbook of Modern Ferromagnetic Materials is an up-to-the-minute compendium of all ferromagnetic materials, metallic and ceramic, intended for electrical and electronic applications. Coverage of the newest and most economically important materials (soft ferrites, the rare-earth magnet alloys, amorphous and nanocrystalline alloys) is extensive. The distinctive feature of this book is its correlation of basic material properties (metallurgical and ceramic) with their magnetic characteristics and eventually to the choice in an application. Unique to this work is information on the many magnetic components into which these materials can be formed and the pertinent design data. Another useful feature is the criteria (quality, stability and economic) for selection of a particular material. Included are the mechanical, thermal and physical properties of these materials. The author not only presents the latest information from suppliers and magnetism conferences but includes a section on new materials (e.g. colossal magnetostriction materials) being developed but not yet available. The format is arranged according to frequency of operation, which turns out to be almost concurrent with the application. Thus, direct current applications are considered first, then low frequency line power, followed by applications at increasing frequencies up to microwave uses. This anthology of ferromagnetic materials is an essential reference work for electrical and electronic designers and materials scientists. It may also serve as a text for a magnetic materials course and as a materials guide for purchasing agents and technical executives.
