Outline of Final Research Achievements

Scanning superconducting quantum interference device (SQUID) microscopy (SSM) enables us to visualize one by one each quantized flux (fluxon) and we proposed a method to observe current flow and fluxon simultaneously by SSM. The objective of this study is to observe fluxons directly around the grain boundaries with structure in which fluxons can be driven in a specific direction. Fluxons were observed in superconducting thin films with an artificial grain boundary. Immersions of the quantized flux into the grain boundary were successfully observed. Calculations were also carried out to determine current flows around non-circular antidots. Further, improvement of the quality of superconducting thin films was carried out. We have succeeded in fabricating and characterizing non-c axis oriented thin films with a new growth mode. Textures of Josephson vortices were observed in the film and the material was found to be suitable for this study.
