Inhaltszusammenfassung
Up to now it is a controversially discussed question whether the Kosterlitz-Thouless (KT) theory can be applied to the high temperature superconductors. Despite of experimental evidences there are theoretical reservations mainly based on the finite anisotropy and resulting linear contributions to the logarithmic vortex-antivortex interaction. A considerable number of experimental results however can be consistently explained by the less-restrictive 2D-Coulomb-gas approach. Highly anisotropic,...Up to now it is a controversially discussed question whether the Kosterlitz-Thouless (KT) theory can be applied to the high temperature superconductors. Despite of experimental evidences there are theoretical reservations mainly based on the finite anisotropy and resulting linear contributions to the logarithmic vortex-antivortex interaction. A considerable number of experimental results however can be consistently explained by the less-restrictive 2D-Coulomb-gas approach. Highly anisotropic, epitaxial Bi-2212 thin films with a mass-anisotropy parameter exceeding 150 offer a model system for the study of these aspects of vortex dynamics in quasi 2D-superconductors.» weiterlesen» einklappen
