Book Synopsis Electromagnetic, Magnetostatic, and Exchange-interaction Vortices in Confined Magnetic Structures by : Eugene Kamenetskii
Download or read book Electromagnetic, Magnetostatic, and Exchange-interaction Vortices in Confined Magnetic Structures written by Eugene Kamenetskii and published by . This book was released on 2008-01-01 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is currently much interest in studying vortex behaviors in different kinds of physical phenomena. Vortices can be easily observed in water. They are well recognized effects in plasma and atmospheric science. In vacuum, one can observe electromagnetic processes with broken symmetry characterizing by different topological effects. Manifestations of phase singularities in optical vortices have opened up a new frontier in optics. There is a large variety of vortex phenomena in condensed matter. It is well known that when a system consisting of many interacting particles is set rotating, it may form vortices. The concept of a vortex is at the center of our understanding of superfluidity. Vortices can appear in magnetically ordered structures and in Bose-Einstein condensates. In the vortex description, there can be used classical or quantum approaches. Vortices can or cannot carry the angular momentum. They can or cannot be characterized by some invariant, such as the flux of vorticity. In spite of the fact that vortices are in common occurrence in many physical problems, it seems very difficult at present to introduce an all-inclusive definition of such 'swirling' entities. Although not being an exhaustive treatise on vortices, this book intends to give a general overview on recent research topics on vortex phenomena in confined magnetic structures. In magnetic structures one can clearly distinguish three characteristic scales. There are the scales of the spin (exchange interaction) fields, the magnetostatic (dipole-dipole interaction) fields, and the electromagnetic fields. These characteristic scales may define different vortex states. It has been shown that in micrometer- or submicrometer-size ferromagnetic dots a magnetization vortex structure will be stable because of competition between the exchange and magnetic dipole interactions. Such magnetic vortices are topologically distinct and robust magnetic states. This stability has a potential as a unit cell for high density magnetic storage and magnetic logic devices. Magnetic vortex dynamics is closely related to their topological structure. One can observe chiral symmetry violation of the vortex states in ferromagnetic dots. A mechanism for changing the topological number of a magnetic configuration makes it possible to obtain controlled switching between the vortex structures. The influence of the vortices on the magnetization reversal was observed in thin ferromagnetic elements. There is a strong interest in study and implementation of vortex states in periodic arrays of magnetic dots. In dilute atomic Bose-Einstein condensates with spin degrees of freedom (the so-called spinor condensates), the anisotropic nature of the dipole interaction greatly enriches the dynamic properties of atoms. The interplay between the dipolar interaction and the spin exchange interaction may lead to the vortex state in the Bose-Einstein condensates that is analogous to the magnetic vortex found in thin magnetic films. Quantized vortices in BECs manifest the long-range phase coherence of many-particle quantum systems which are described by a complex-valued order parameter field, and their existence and stability is intimately related to the superfluid properties of the system. The dipole interaction provides us with a long-range mechanism of interaction. The importance of magnetostatic energy increases gradually as the magnetic structure size increases. Magnetostatic ferromagnetism has a character essentially different from exchange ferromagnetism. This statement finds strong confirmation in confinement phenomena of magnetic-dipolar-mode oscillations. In magnetic structures with the sizes from several micrometers up to tens of micrometers, one can observe peculiar magnetostatic (or magnetic-dipolar-mode) vortices. In quasi-2D magnetic-dipolar-mode ferrite disks two kinds of quantum-like conservation rules are encounted: the symmetry conservation and the double-valued-function electric flux quantization. The interplay between these conservation rules gives rise to unique vortex patterns. It is very interesting that together with the exchange-interaction and magnetic-dipolar vortex behaviors, electromagnetic (Poynting-vector) vortices can exist in ferromagnetic systems. A ferrite is a magnetic dielectric with low losses. This may allow for electromagnetic waves to penetrate the ferrite and results in an effective interaction between the electromagnetic waves and magnetization within the ferrite. At the ferromagnetic resonance conditions, such an interaction can demonstrate the electromagnetic vortex behaviors. One of the most exciting thing is that there can be found a certain resemblance between topological structures of phase singularities in quasi-2D electromagnetic and magnetization patterns. The book has 21 chapters. The chapters were written by top experts from 18 countries (Italy, Ukraine, UK, Mexico, USA, China, Germany, Brazil, Japan, Russia, France, Chile, Finland, Singapore, Greece, India, Canada, and Israel), who have contributed significantly to the advancement of the science and engineering of the magnetic vortex behaviors. I hope that the book will be a valuable aid to understand current studies in vortex phenomena in magnetic structures for scientists, researchers, and graduate students working in the field of electronic engineering, materials science, and condense matter physics. I would like to express my thanks to all of the authors who accepted my invitation to contribute the respective chapters. I would like to acknowledge Dr. S. G. Pandalai at Transworld Research Network for his invitation to me of editing this book. I would like to thank Prof. Reuven Shavit at the Electrical and Computer Engineering Department of Ben Gurion University of the Negev for his interest in new vortex behaviors in microwave magnetic systems, useful discussions, and valuable support in realization of this project.

Book Synopsis Electromagnetic Absorption in the Copper Oxide Superconductors by : Frank J. Owens
Download or read book Electromagnetic Absorption in the Copper Oxide Superconductors written by Frank J. Owens and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1987 a major breakthrough occurred in materials science. A new family of materials was discovered that became superconducting above the temperature at which nitrogen gas liquifies, namely, 77 K or –196°C. Within months of the discovery, a wide variety of experimental techniques were brought to bear in order to measure the properties of these materials and to gain an understanding of why they superconduct at such high temperatures. Among the techniques used were electromagnetic absorption in both the normal and the superconducting states. The measurements enabled the determination of a wide variety of properties, and in some instances led to the observation of new effects not seen by other measu- ments, such as the existence of weak-link microwave absorption at low dc magnetic fields. The number of different properties and the degree of detail that can be obtained from magnetic field- and temperature-dependent studies of electromagnetic abso- tion are not widely appreciated. For example, these measurements can provide information on the band gap, critical fields, the H–T irreversibility line, the amount of trapped flux, and even information about the symmetry of the wave function of the Cooper pairs. It is possible to use low dc magnetic field-induced absorption of microwaves with derivative detection to verify the presence of superconductivity in a matter of minutes, and the measurements are often more straightforward than others. For example, they do not require the physical contact with the sample that is necessary when using four-probe resistivity to detect superconductivity.
Book Synopsis Fields of Force by : William Berkson
Download or read book Fields of Force written by William Berkson and published by Routledge. This book was released on 2014-05-09 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the picture of reality given by Newton, and the development of the later picture of reality given by field theory. In telling this story, the author explains what problem each scientist faced, and how the process of solving them led to new discoveries. By this method he gives unique insight into the understanding of Einstein’s special theory of relativity, as he explains exactly what problems led to the invention of the theory, and exactly where Einstein’s solution differed from his predecessors’. A similar analysis is given of the discoveries of Faraday, Maxwell, Hertz and Lorentz. The problem-oriented approach of the book, originally published in 1974, enables the reader to share in the original creative process, and in the excitement of the discoveries. It puts physics problems into new perspective and discusses the philosophical implications of the history - an illuminating account of a great episode in the history of thought.

Available in PDF, EPUB and Kindle. Book excerpt: For a few seconds with large machines, scientists and engineers have now created the fusion power of the stars in the laboratory and at the same time find the rich range of complex turbulent electromagnetic waves that transport the plasma confinement systems. The turbulent transport mechanisms created in the laboratory are explained in detail in the second edition of "Turbulent Transport in Magnetized Plasmas" by Professor Horton. The principles and properties of the major plasma confinement machines are explored with basic physics to the extent currently understood. For the observational laws that are not understood — the empirical confinement laws — offering challenges to the next generation of plasma students and researchers — are explained in detail. An example, is the confinement regime — called the "I–mode" — currently a hot topic — is explored. Numerous important problems and puzzles for the next generation of plasma scientists are explained. There is growing demand for new simulation codes utilizing the massively parallel computers with MPI and GPU methods. When the 20 billion dollar ITER machine is tested in the 2020ies, new theories and faster/smarter computer simulations running in near real-time control systems will be used to control the burning hydrogen plasmas.
Book Synopsis Visualization in Science Education by : John K. Gilbert
Download or read book Visualization in Science Education written by John K. Gilbert and published by Springer Science & Business Media. This book was released on 2005-07-05 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visualization, meaning both the perception of an object that is seen or touched and the mental imagery that is the product of that perception, is believed to be a major strategy in all thought. It is particularly important in science, which seeks causal explanations for phenomena in the world-as-experienced. Visualization must therefore play a major role in science education. This book addresses key issues concerning visualization in the teaching and learning of science at any level in educational systems. ‘Visualization in Science Education’ draws on the insights from cognitive psychology, science, and education, by experts from Australia, Israel, Slovenia, UK, and USA. It unites these with the practice of science education, particularly the ever-increasing use of computer-managed modelling packages, especially in chemistry. The first section explores the significance and intellectual standing of visualization. The second section shows how the skills of visualization have been developed practically in science education. This is followed by accounts of how the educational value of visualization has been integrated into university courses in physics, genomics, and geology. The fourth section documents experimental work on the classroom assessment of visualization. An endpiece summarises some of the research and development needed if the contribution of this set of universal skills is to be fully exploited at all levels and in all science subjects.
