AbstractAbstract
[en] Gaussian fluctuations in layered superconductors have been the subject of study for many years. Although the FD was studied in detail long ago, the FC (fluctuation conductivity) was studied only recently, since the MT and DOS diagrams were previously neglected. Recent comparisons with experiment on YBCO have shown that the DOS diagrams are important and can lead to qualitatively different behaviors for the FC parallel and perpendicular to the layers. In both cases, Gaussian fluctuations fit the data above Tc very well, even for YBCO. To date, nearly all calculations of fluctuation quantities were for B parallel c. Nevertheless, it should be possible to treat an arbitrary B, but the evaluation of the required matrix elements for the fluctuation quantities will be more complicated

AbstractAbstract
[en] Vibrating reed measurements were performed on single-crystal samples of k-(ET)2-Cu[N(CN)2]Br in an applied magnetic field H oriented either parallel (open-quotes longitudinalclose quotes) or perpendicular (open-quotes transverseclose quotes) to the highly conducting ac-plane. Field-cooling data taken for the longitudinal orientation and H < 0.7 T revealed a peak with a low-temperature shoulder in the reed dissipation 1/Q located at temperature TQ below the superconducting transition temperature Tc (∼ 11.6 for H=0). The shoulder disappeared near H∼ 0.7 T, accompanied by an abrupt change in the slope of TQ(H), corresponding to a similar change in the slope of the upper critical magnetic field Hc2 measured by Kwok et al. The existence of the shoulder in the dissipation peak bears on a number of current explanations for the exotic superconducting properties of k-(ET)2Cu[N(CN)2]Br. TQ data taken for the transverse orientation fell far below estimates of Hc2, indicating the existence of a substantial region of flux line (FL) mobility below Hc2(T). The location of a peak in NMR relaxation by De Soto et al. lies close to TQ for the transverse orientation

AbstractAbstract
[en] Comprehensive and easy to understand, this introductory text on superconductivity was especially written for the non-specialist. The author, an active researcher in the field for more than forty years, first presents the fundamental considerations - without too much mathematics. He describes the various phenomena connected with the superconducting state, provides experimental facts and discusses numerous examples for modern applications. The new high-temperature superconductors are also dealt with in detail. For almost two decades now, the German version of this book - currently in its fourth edition - has been the best-selling standard work on superconductivity. (orig.)

AbstractAbstract
[en] The purpose of this thesis is to investigate whether a BCS-like theory sufficiently describes the superconducting state of high temperature superconductors (HTSC). An important feature of HTSC is the large anisotropy. Therefore a cylindersymmetrical model Fermi surface is introduced. The critical temperature Tc, the energy gap and the specific heat are calculated for an hour-glass shaped Fermi surface. Its limiting case of a cylindrical Fermi surface is used to investigate the magnetic penetration depth and the upper critical field Bc2. The results are compared with calculations for the standard isotropic model having a spherical Fermi surface. It is found that the properties of the superconducting state depend substantially on the material parameters of the normal metal, and this dependence can be significantly different for the various Fermi surface models. Finally the theory is used to study the properties of the HTSC YBa2Cu3O7. (Author, shortened by G.Q.)

In dieser Dissertation wird die Anwendbarkeit einer BCS-artigen Theorie auf Hochtemperatursupraleiter (HTSL) untersucht. Als charakteristische Eigenschaft der HTSL findet dabei die hohe Anisotropie bedeutender physikalischer Eigenschaften Beruecksichtigung, wozu das Modell einer zylindersymmetrischen Fermiflaeche eingefuehrt wird. Fuer eine Fermiflaeche von der Form einer Sanduhr werden die kritische Temperatur Tc, die Energieluecke und die spezifische Waerme untersucht und fuer deren Grenzfall einer zylindrischen Fermiflaeche zusaetzlich das obere kritische Magnetfeld Bc2 und die magnetische Eindringtiefe lambda. Die Resultate werden mit Ergebnissen der ueblichen isotropen Theorie verglichen. Dabei findet man, dasz der enge Zusammenhang zwischen den Parametern des supraleitenden Zustands und den Groeszen zur Beschreibung des normalleitenden Metalls fuer verschiedene Fermiflaechenmodelle durchaus unterschiedlich sein kann. Schlieszlich ermoeglicht die Anwendung der Theorie auf den HTSL YBa2Cu3O7, aus Meszergebnissen fuer Tc, Bc2 und lambda einen konsistenten Satz von Parametern des normalleitenden Zustands zu ermitteln.

AbstractAbstract
[en] In order to clarify the mechanism of organic superconductor β-(BDA-TTP) salts. We study the superconductivity under uniaxial compression with non-dimerized two-band Hubbard model. We have calculated the uniaxial compression dependence of Tc by solving the Eliashberg's equation using the fluctuation exchange (FLEX) approximation. The transfer integral under the uniaxial compression was estimated by the extended Huckel method. We have found that non-monotonic behaviors of Tc in experimental results under uniaxial compression are understood taking the spin frustration and spin fluctuation into account.

AbstractAbstract
[en] The use of high-temperature superconductors (HTSC) for device application has made the compatibility of the film and substrate an important concern. The quest for an ideal substrate material for the growth of HTSC films with excellent properties for device applications is an active area of research and needs further investigation. We have examined garnet as a potential substrate material suitable for microwave applications, and we compare its various physical properties with those of other well-known substrate materials.
