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.

The word "magnet" refers to the material having both directive and attractive property. The magnet with its two such distinct and significant properties have attracted common man as well as researcher because of its obvious applications in various fields like electronic, electrical telecommunication, biomedical, power, food, automobile, construction, recording media and computer industries. Research in this area has gained momentum since 1914. It focuses on synthesis, characterization, functionalization of the properties of these materials for betterment of human life in the society.

This book is devoted to an entirely new direction of the magnetoelectronics of millimetric waves in layered structures containing epitaxial ferrite films. End of chapter references provide additional background information on the topics discussed.

This book provides a state-of-the-art survey of the behaviour and principal applications of electronic ceramics including their magnetic, ferroelectric, electronic and ionic conducting properties.

The first natural magnetic material found to man in pre historic time was magnetite (Fe3O4), which is now known as ferrous ferrite. The story of ferrites begins with the search for ferromagnetic material of usual high resistivity to obtain reasonable low eddy current losses. When ferrimagnetic materials placed in alternating field, eddy current generates into them, which dissipates energy. These losses can be reduced by lamination of ferrimagnetic core to restrict eddy current. Since, eddy current losses are inversely proportional to the resistivity; they can be minimized by use of magnetic materials of high resistivity. Ferrites having resistivity of up to 107Ωm as compared to 10-7Ωm of iron, reduces the eddy current losses in them to a negligible value, even at microwave frequencies.

Presents a comprehensive and interdisciplinary review of the major cutting-edge technology research areas—especially those on new materials and methods as well as advanced structures and properties—for various sensor and detection devices The development of sensors and detectors at macroscopic or nanometric scale is the driving force stimulating research in sensing materials and technology for accurate detection in solid, liquid, or gas phases; contact or non-contact configurations; or multiple sensing. The emphasis on reduced-scale detection techniques requires the use of new materials and methods. These techniques offer appealing perspectives given by spin crossover organic, inorganic, and composite materials that could be unique for sensor fabrication. The influence of the length, composition, and conformation structure of materials on their properties, and the possibility of adjusting sensing properties by doping or adding the side-groups, are indicative of the starting point of multifarious sensing. The role of intermolecular interactions, polymer and ordered phase formation, as well as behavior under pressure and magnetic and electric fields are also important facts for processing ultra-sensing materials. The 15 chapters written by senior researchers in Advanced Sensor and Detection Materials cover all these subjects and key features under three foci: 1) principals and perspectives, 2) new materials and methods, and 3) advanced structures and properties for various sensor devices.
