High Tc Superconductor Materials

The dynamic developments in high-temperature superconductivity over the last three years has augmented the importance of materials research not only for applications, but also for the understanding of underlying physical phenomena. The discovery of new superconductors has opened up new facets of High Tc research, and the perfection of already known materials has enabled reliable physical measurements to be carried out, providing a foundation for theoretical models. The papers in this volume present an overview of the recent developments in the field of High Tc-materials research. One of the highlights of this meeting was the plenary lecture by the Nobel laureate K. Alex Müller on the importance of the apical oxygen phenomena which are strongly connected with Tc changes.

High Tc Superconductor Thin Films

Interdisciplinary research on superconducting oxides is the main focus of the contributions in this volume. Several aspects of the thin film field from fundamental properties to applications are examined. Interesting results for the Bi system are also reviewed. The 132 papers, including 8 invited, report mainly on the 1-2-3 system, indicating that the Y-Ba-Cu-O and related compounds are still the most intensively studied materials in this field. The volume attests to the significant progress that has been made in this field, as well as reporting on the challenging problems that still remain to be solved.

The articles in this exceptional book contain regular papers, extended papers and reviews, and thus vary in length and are useful for all kinds of audience. They describe, as the book's name suggests, HTSC models and methodologies. Physical models (like extended BCS model, bipolaron model, spin bag model, RVB (resonating valence bond) model, preformed Cooper pairs and antiferromagnetic spin fluctuation (AFSF) based models, stripe phase, paired cluster (spin glass (SG) frustration based) model, Kamimura-Suwa (Hund's coupling mechanism based) model, electron- plasmon interaction, electron- phonon interaction, etc.), theoretical methods (methodologies) (like generalised BCS-Migdal-Eliashberg theory, Hubbard model, t-J model, t-t'-U model, Hubbard-Holstein model, Fermi-, non Fermi- and marginal Fermi- liquid concepts, generalised Hartree-Fock formalism, etc.) and, experimental status and methodologies are all described there. For comparison with cuprates, fullerenes, ruthenates, organic-, non Cu-containing oxide-and conventional (elemental, A15)- superconductors, molecular crystals, nickelates, manganites, borides etc. are also discussed.

Since the discovery in 1986 of high temperature superconductors by J. G. Bednorz and K. A. Müller, a considerable progress has been made and several important scientific problems have emerged. Within this NATO Advanced Study Institute our intention was to focus mainly on the controversial topic of the symmetry of the superconducting gap and given the very short coherence length, the role of fluctuations. The Institute on ‘The Gap Symmetry and Fluctuations in High- Superconductors’ took place in the “Institut d’Etudes Scientifiques de Cargèse” in Corsica, France, between 1 - 13 September 1997. The 110 participantsfrom 18 countries (yet 30 nationalities) including 23 full time lecturers, have spent two memorable weeks in this charming Mediterranean resort. All lecturers were asked to prepare pedagogical papers to clearly present the central physical idea behind specific model or experiment. The better understanding of physics of high temperature superconductivity is certainly needed to guide the development of applications of these materials in high and weak current devices.

Electron-phonon Interaction And Lattice Dynamics In High Tc Superconductors

Understanding the mechanism of the high-temperature superconductors has been a very important topic in condensed matter physics. Researchers have been trying to explain the role of electron-phonon interaction (EPI) in cuprates. Some important properties of the cuprates could not be explained by conventional BCS theory. This book contains the experimental and theoretical studies on the EPI. The experimental part covers the results of angle-resolved photoemission spectroscopy (ARPES), isotopic effect, elastic neutron scattering study of electron-phonon, lattice role and so on. The theoretical part covers the electron-phonon, polaron and bipolaron, effect of lattice, fine structure in the tunnelling spectra of electron-doped cuprates, identification of the bulk pairing symmetry in high-temperature superconductors.Students and researchers interested in high-temperature superconductors, especially the EPI in cuprates will find this title very useful.
