Abstract:
The work carried out under this grant has been the investigation of thin films and single crystals of the layered cuprate high-temperature superconductors, as well as other model systems. A primary objective in the program was the development of a better understanding of the limits of the occurrence of superconductors with high transition temperature above liquid nitrogen temperature. The work is thus composed of an empirical part that searches for superconductivity by similarities and chemical guidance as well as critical tests for various theories of the high-Tc mechanism. Another aspect of the program was to study the superconducting and normal state properties in applied magnetic fields, in particular we studied the coupling between the Cu-O layers in superlattices. We employed the artificially layered Superconductor insulator system of MoGeGe which have in-plane and out-of plane anisotropies which bracket those found in the layered cuprates model system.
