Summary

SUPERCONDUCTING FILMS OF THIS HIGH CRITICAL TEMPERATURE COMPOUND HAVE BEEN GROWN ON (111)-ORIENTED GADOLINIUM GALLIUM GARNET SUBSTRATES BY A LIQUID-PHASE TECHNIQUE. THE FILMS SHOW A VERY HIGH DEGREEOF PREFERENTIAL ORIENTATION WITH THE C-AXIS PERPENDICULAR TO THE SUBSTRATES. THE ONSET OF THE RESISTIVE TRANSITION WAS 85 K WHILE ZERO RESISTANCE WAS OBTAINED AT 78 K. RESULTS CONCERNING THE CRITICAL CURRENT PROPERTIES OF THE FILMS ARE DESCRIBED. MEASUREMENTS OF THE PARACONDUCTIVITY EFFECTS ON THE ELECTRICAL RESISTIVITY ABOVE THE SUPERCONDUCTING TRANSITION DUE TO THERMODYNAMIC FLUCTUATIONS ARE ALSO REPORTED.
