Paper Abstract

Single target in situ sputter deposition using 9O off-axis geometry has made it possible to study various physical properties of superconducting films of YBaCu3O'x under well controlled conditions. The superconducting DC and high frequency properties, and the normal state properties can all be optimized under conditions which do not necessarily produce the highest Tc's. Surface resistances at 4.2 K and 10 GHz are reproducibly less than 20 iQ. Correlations between the processing parameters, DC properties, microstructures and high frequency properties of these films as they are presently known are summarized.
