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.

Below is a copy of Professor Takeshi Takei's original preface that he wrote for my first book, Modem Ferrite Teclmology. I was proud to receive this preface and include it here with pride and affection. We were saddened to learn of his death at 92 on March 12, 1992. Preface It is now some 50 years since ferrites debuted as an important new category of magnetic materials. They were prized for a range of properties that had no equivalents in existing metal magnetic materials, and it was not long before full-fledged research and development efforts were underway. Today, ferrites are employed in a truly wide range of applications, and the efforts of the many men and women working in the field are yielding many highly intriguing results. New, high-performance products are appearing one after another, and it would seem we have only scratched the surface of the hidden possibilities of these fascinating materials. Dr. Alex Goldman is well qualified to talk about the state of the art in ferrites. For many years Dr. Goldman has been heavily involved in the field as director of the research and development division of Spang & Co. and other enterprises. This book, Modem Ferrite Technology, based in part on his own experiences, presents a valuable overview of the field. It is testimony to his commitment and bountiful knowledge about one oftoday's most intriguing areas of technology.

This book summarizes the state-of-the-art knowledge on ferrites as well as the cutting-edge applications of these versatile materials. The main families of ferrites and their modern synthesis and processing methods are covered in this review book. Furthermore, the different morphologies of these materials and their current and incipient applications are also discussed.

This book has given an overview of the sol-gel auto-combustion preparation method and characterization of Ni0.5Co0.5FeCrO4. This work focused on the structural properties XRD,TGA, SEM, TEM, FTIR, Magnetic Properties, Dielectric Properties were measured.By using the TG curve the exact temperature of formation of ferrite phase was obtained.The properties such as dielectric constant, dielectric loss tangent as a function of frequency and temperature. The addition of chromium in nickel – cobalt ferrite significantly changes the electrical and magnetic properties. Nickel and cobalt ferrites are inverse ferrites and hence for x £ 1, nickel ferrite shows structure of inverse spinel and for x >1, the inverse structure converted into normal structure. The crystal structure of ferrite, cation distribution, synthesis route, sintering conditions, amount and type of impurity addition decides the electric and magnetic properties of ferrites. Same ferrite with different crystalline size shows different properties. The electrical and magnetic properties even structural properties of ferrites at nano-crystalline phase shows significantly difference than the bulk one. In the present investigation we have presented the results on structural and magnetic properties of Ni0.5Co0.5FeCrO4 sintered at 5000C, 6000C, 7000C and 8000C for 6h.

This proceedings includes 147 papers covering the latest scientific and technological developments in ferrites and related materials in three broad subject categories: Basic Science, Processing and Applications, and Special Topics and New Horizons. There are two main categories for ferrites: hard ferrites (permanent magnets) and soft ferrites. Topics covered are energy conversion, magnetite biomineralization, microwave ferrites, magneto-optical properties and applications of ferrite films, bonded magnets, physics of electronic superstructures in magnetite, physics of perovskites, nanostructural ferrites, and multilayer chip inductors.
