Book Description
The authors of this book present current research in the study of superconductivity. Topics discussed in this compilation include the effects of non-magnetic defects in hole doped cuprates; deep cryogenic refrigeration by photons based on the phonon deficit effect in superconductors; superconductivity driven by an anti-polar electric phase in high temperature superconducting materials; superconductive graphite intercalation compounds; a superconducting magnetic field concentrator with nanodimensional branches and slits; magnetic mechanisms of pairing in a strongly correlated electron system of copper oxides; two non-linear mechanisms of correlations between copper carriers in superconductivity and their microscopical descriptions; three dimensionality of the critical state and variational methods for magnetically anisotropic superconductors; theory of multi-band superconductivity; conserving approximation for the self-energy of the t-U-V-J model beyond the Hartree-Fock approximation; and superconductivity as a consequence of an ordering of zero-point oscillations in electron gas.

Book Description
The workshop focussed on issues related to Bulk Processing and Applications, Structure and Flux Pinning as well as Thin Films. These issues are currently very critical to the development of these superconductors.Fifty-two papers authored by researchers from the United States and Japan were presented at the workshop. They reflect the state of the field in high-Tc superconductors and the direction in which the technology in these superconductors is moving. The papers also make accessible to interested scientists and engineers extremely valuable information on the progress achieved in applications in recent years.

Book Description
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, 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. This Publication presents new research on yttrium barium copper oxide superconductors, often abbreviated YBCO, which is a chemical compound with the formula YBa2Cu3O7. This material, a famous 'high-temperature superconductor', achieved prominence because it was the first material to superconduct above the boiling point of nitrogen. All materials developed before YBCO became superconducting only at temperatures near the boiling points of liquid helium or liquid hydrogen (Tb = 20.1 K). The significance of the discovery of YBCO is the breakthrough in the refrigerant used to cool the material to below the critical temperature.

Book Description
In contrast to research on the fundamental mechanisms of High-Temperature Superconductivity, in recent years we have seen enormous developments in the fabrication and application of High-Tc-superconductors. The two volumes of High Temperature Superconductivity provide a survey of the state of the technology and engineering applications of these materials. They comprise extended original research papers and technical review articles written by physicists, chemists, materials scientists and engineers, all of them noted experts in their fields. The interdisciplinary and strictly application-oriented coverage should benefit graduate students and academic researchers in the mentioned areas as well as industrial experts. Volume 1 "Materials" focuses on major technical advancements in High-Tc materials processing for applications. Volume 2 "Engineering Applications" covers numerous application areas where High-Tc superconductors are making tremendous impact.
