Abstract:

High temperature superconductor composite thin film devices with easily moved Josephson vortices are described having high Tsub c and good magnetic vortex properties. A preferred composite material was YBCOCeOsub 2 thin film on a MgO substrate. The superconductor composites were preferably formed by off-axis co-sputtering. A surprising recovery in properties was seen after plasma etching with oxygen.
