Book excerpt: Measurements of critical currents were performed on planar and cylindrical films of tin of 650 to 2500 A thickness. Both pulsed currents (80 nanoseconds duration) and dc currents with stabilizing network were used. Close agreement was obtained for the dc data in the temperature dependence and approximate agreement in the magnitude of the critical current when compared with Bardeen's calculation as long as the stabilizing network was effective. The pulse measurements deviate from theory and the dc data for temperatures T/T sub c

Book Synopsis Magnetic Susceptibility of Superconductors and Other Spin Systems by : T.L. Francavilla
Download or read book Magnetic Susceptibility of Superconductors and Other Spin Systems written by T.L. Francavilla and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop entitled Magnetic Susceptibility of Superconductors and other Spin Systems (S4) was held at Coolfont Resort and Health Spa. located near Berkley Springs West Virginia on May 20-23. 1991. There were over sixty attendees. approximately half from the United States. the remainder representing over twelve different countries. The international character of the workshop may be gleaned form the attendee list, included in this volume. The intent of the workshop was to bring together those experimentalists and theoreticians whose efforts have resulted in significant recent contributions to the development and use of the ac susceptibility technique as well as to the interpretation of data obtained from these measurements. Many spirited discussions occurred during and after the presentations. These are reflected in the manuscripts contained in these proceedings. Although camera ready manuscripts were required from all participants at registration, all manuscripts were revised and reflect the lively exchanges that followed each presentation. The small size of the workshop allowed the participants a high degree of flexibility. Consequently when a controversial topic such as "the irreversibility line" emerged, a special session was organized on the spot. At the suggestion of Ron Goldfarb, participants were invited to contribute a one page summary containing their thoughts on the topic. These stand alone contributions were retyped and included as submitted, with only minor editorial changes. These proceedings are intended for those experienced scientists new to the field and graduate students just beginning their research.

The authors presented investigations of traditional and new materials. In particular, studies of oxides, pnictides, chalcogenides and intermetallic compounds are included. The superconducting order parameter symmetry is discussed and consequences of its actual non-conventional symmetry are studied. Impurity and tunneling effects (both quasiparticle and Josephson ones) are among topics covered in the chapters. Special attention is paid to the competition between superconductivity and other instabilities, which lead to the Fermi surface gapping.
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 208 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 Superconductivity, Magnetism and Magnets by : Lannie K. Tran
Download or read book Superconductivity, Magnetism and Magnets written by Lannie K. Tran and published by Nova Publishers. This book was released on 2006 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. Many universities, research institutes and companies are working to develop high-Tc superconductivity applications and considerable progress has been made. This volume brings together new leading-edge research in the field.
Book Synopsis Applied Superconductivity by : Vernon L. Newhouse
Download or read book Applied Superconductivity written by Vernon L. Newhouse and published by Academic Press. This book was released on 2013-10-22 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Superconductivity, Volume II, is part of a two-volume series on applied superconductivity. The first volume dealt with electronic applications and radiation detection, and contains a chapter on liquid helium refrigeration. The present volume discusses magnets, electromechanical applications, accelerators, and microwave and rf devices. The book opens with a chapter on high-field superconducting magnets, covering applications and magnet design. Subsequent chapters discuss superconductive machinery such as superconductive bearings and motors; rf superconducting devices; and future prospects in applied superconductivity. Each chapter in the two volumes can be read independently, and most assume very little or no background in the physics of superconductivity. The topics treated do not require the use of advanced quantum mechanics; thus the books should be accessible to students or research workers in any branch of engineering or physics. They are intended to serve both as a source of reference material to existing techniques and as a guide to future research.
