This book has been written to introduce readers to group theory and its ap plications in atomic physics, molecular physics, and solid-state physics. The first Japanese edition was published in 1976. The present English edi tion has been translated by the authors from the revised and enlarged edition of 1980. In translation, slight modifications have been made in. Chaps. 8 and 14 to update and condense the contents, together with some minor additions and improvements throughout the volume. The authors cordially thank Professor J. L. Birman and Professor M. Car dona, who encouraged them to prepare the English translation. Tokyo, January 1990 T. Inui . Y. Tanabe Y. Onodera Preface to the Japane...
In the quest for higher data density in information technology manipulation of magnetization by other means than magnetic fields has become an important challenge. This lead to a startling revival of the magnetoelectric effect, which characterizes induction of a polarization by a magnetic field or of a magnetization by an electric field. The magnetoelectric crosslink of material properties opens just those degrees of freedom which are needed for the mutual control of magnetic and electric states. The book gives a state-of-the-art review on magnetoelectrics research, classifies current research tendencies, and points out possible future trends. Novel compounds and growth techniques and new theoretical concepts for the understanding of magnetoelectric coupling phenomena are introduced. Highlights are the discovery of "gigantic" magnetoelectric effects which are strong enough to trigger electric or magnetic phase transitions; the concept of magnetochirality; and development "structural" magnetoelectric effects in artificial multiphase compounds. The book is addressed to condensed-matter physicists with a particular focus on experts in highly correlated systems.
Magnetism, Volume I: Magnetic Ions in Insulators: Their Interactions, Resonances, and Optical Properties summarizes the understanding of magnetically ordered materials. This book contains 12 chapters that specifically tackle the concepts of ferromagnetism, ferrimagnetism, and antiferromagnetism. After briefly dealing with the spin Hamiltonians of typical ions and the interactions between the ions, this book goes on discussing the diverse aspects of ferromagnetism, ferrimagnetism, and antiferromagnetism in insulators as well as in metals. These topics are followed by presentation of abstract quantum mechanical and statistical models and the theory of spin interactions in solids. The other chapters describe the actual magnetic structures and the phenomenology of ferromagnets. This text further considers the fundamentals of neutron diffraction and optical phenomena in magnetically ordered materials. The concluding chapters look into the cooperative phenomena characterized by ordered arrangements of magnetic moments subject to strong mutual interactions. Physicists and magnetism researchers will find this book of great value.
Profiles over 200 scientists from around the world who made important contributions to the interdisciplinary field of science, technology and society (STS), including Thomas P. Ackerman, Helen Caldicott, James Watt, and more.
Although several books and conference proceedings have already appeared dealing with either the mathematical aspects or applications of homogenization theory, there seems to be no comprehensive volume dealing with both aspects. The present volume is meant to fill this gap, at least partially, and deals with recent developments in nonlinear homogenization emphasizing applications of current interest. It contains thirteen key lectures presented at the NATO Advanced Workshop on Nonlinear Homogenization and Its Applications to Composites, Polycrystals and Smart Materials. The list of thirty one contributed papers is also appended. The key lectures cover both fundamental, mathematical aspects of ...
This volume contains the lectures and seminars presented at the NATO Advanced Study Institute on "Physics of New Laser Sources", the twelfth course of the Europhysics School of Quantum Electronics, held under the supervision of the Quantum Electronics Division of the European Physical Society. The Institute was held at Centro "I Cappuccini" San Miniato, Tuscany, July 11-21, 1984. The Europhysics School of Quantum Electronics was started in 1970 with the aim of providing instruction for young researchers and advanced students already engaged in the area of quantum electronics or for those wishing to switch into this area after working previously in other areas. From the outset, the School has...
Contains short biographies of almost 1,000 scientists from around the world who made great contributions to science throughout history.
