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 The Physics and Chemistry of Nanosolids by : Frank J. Owens
Download or read book The Physics and Chemistry of Nanosolids written by Frank J. Owens and published by John Wiley & Sons. This book was released on 2008-04-11 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive textbook that addresses the recent interest in nanotechnology in the engineering, materials science, chemistry, and physics communities In recent years, nanotechnology has become one of the most promising and exciting fields of science, triggering an increasing number of university engineering, materials science, chemistry, and physics departments to introduce courses on this emerging topic. Now, Drs. Owens and Poole have revised, updated, and revamped their 2003 work, Introduction to Nanotechnology, to make it more accessible as a textbook for advanced undergraduate- and graduate-level courses on the fascinating field of nanotechnology and nanoscience. The Physics and Chemistry of Nanosolids takes a pedagogical approach to the subject and assumes only an introductory understanding of the physics and chemistry of macroscopic solids and models developed to explain properties, such as the theory of phonon and lattice vibrations and electronic band structure. The authors describe how properties depend on size in the nanometer regime and explain why these changes occur using relatively simple models of the physics and chemistry of the solid state. Additionally, this accessible book: Provides an introductory overview of the basic principles of solids Describes the various methods used to measure the properties of nanosolids Explains how and why properties change when reducing the size of solids to nano-dimensions, and what they predict when one or more dimensions of a solid has a nano-length Presents data on how various properties of solids are affected by nanosizing and examines why these changes occur Contains a chapter entirely devoted to the importance of carbon nanostructured materials and the potential applications of carbon nanostructures The Physics and Chemistry of Nanosolids is complete with a series of exercises at the end of each chapter for readers to enhance their understanding of the material presented, making this an ideal textbook for students and a valuable tutorial for technical professionals and researchers who are interested in learning more about this important topic.
Book Synopsis Stripes and Related Phenomena by : Antonio Bianconi
Download or read book Stripes and Related Phenomena written by Antonio Bianconi and published by Springer Science & Business Media. This book was released on 2006-04-10 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of superconductors has been a central issue in Solid State Physics since 1987. After the discovery of superconductivity (HTSC) in doped perovskites, it was realized that the HTSC appears in an unknown complex electronic phase of c- densed matter. In the early years, all theories of HTSC were focused on the physics of a homogeneous 2D metal with large electron–electron correlations or on a 2D polaron gas. Only after 1990, a novel paradigm started to grow where this 2D metallic phase is described as an inhomogeneous metal. This was the outcome of several experimental evidences of phase separation at low doping. Since 1992, a series of conferences on phase separation were organized to allow scientists to get together to discuss the phase separation and related issues. Following the discovery by the Rome group in 1992 that “the charges move freely mainly in one direction like the water running in the grooves in the corrugated iron foil,” a new scenario to understand superconductivity in the superconductors was open. Because the charges move like rivers, the physics of these materials shifts toward the physics of novel mesoscopic heterostructures and complex electronic solids. Therefore, understanding the striped phases in the perovskites not only provides an opportunity to understand the anomalous metallic state of cuprate superconductors, but also suggests a way to design new materials of technological importance. Indeed, the stripes are becoming a field of general scientific interest.

Book Synopsis Understanding the Superconductivity in Copper Oxides by : Alex K. Muller
Download or read book Understanding the Superconductivity in Copper Oxides written by Alex K. Muller and published by World Scientific Publishing Company. This book was released on 2020-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to clarify the situation by adopting a very different approach from the above electronic/magnetic models, where explicitly local dynamical distortions are considered. These are distinctly different from conventional phonons which are a property of the infinite translational invariant symmetric lattice. The local dynamical distortions are shown to account for bulk properties and provide consistent and quantitative agreement with experimental data together with explicit predictions. Selected published experimental and theoretical papers are presented which support the above arguments, but have been ignored on purpose by the originators of the RVB/t-J bubble. To summarize the scope of this book, comprising nine chapters, it is shown, that the phenomenon of HTS in copper oxides is much better understood than publically claimed by RVB/t-J followers. Using the words of B. Laughlin, the presence of the antiferromagnetism in HTS masks the underlying physics where vibronic bipolarons with spin S=0 are the major players. Furthermore is it worth mentioning, that the newly discovered Fe based layered compounds are rather closely related to the copper oxides which near degenerate bands due to the vibronic coupling of the copper-oxygen units with Jahn-Teller character. Analogous to the latter the Fe based superconductors exhibit almost degenerate wave vector independent bands near the Fermi energy stemming from the tetrahedrally coordinated Jahn-Teller active two-valent iron ion.

Download or read book Advances in Superconductivity VI written by Toshizo Fujita and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1359 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than seven years have passed since the dramatic breakthrough in the critical temperature for superconductors. During this period, a host of new materials have been discovered, and efforts have been stepped up in a variety of domains including device and systems applications, commercialization, and basic research on the properties of superconductive materials. Recent progress in areas such as bulk single crystal production, long-scale wire and tape produc tion, flywheel and bearing applications, and electronic device applications for thin films indicate that science and technology have been working hand in hand in this field, as has been the case in the research and development of semi conductors. This interdisciplinary "resonance" will be certain to lead to further outstanding advances in the years to come. It goes without saying that worldwide information exchange is the key to accelerating progress in superconductivity science and technology. As in previous years, the ISS '93 served as a venue where visions of future develop ments were shared in addition to presentations and extensive discussions on the most up-to-date research results. I hope that the Proceedings contained in this volume will be consulted not only as a summary of the current "state of the art" in high-Tc superconductivity but also as a stimulating source of ideas regarding future applications of superconductivity research.
