Effects of Ag addition on the epitaxially grown YbBa/sub 2/Cu/sub 3/O/sub 7/ superconductor on a SrTiO/sub 3/ (100) substrate by the liquid gas solidification process have been investigated. Ag acts as flux and does not incorporate in the oxide formation. Its addition, however, enhances the transport properties resulting from a reduction in film-substrate interaction. Values of /ital T//sub /ital c//(/ital R/=0)=90 K and /ital J//sub /ital c//(77 K, /ital H/=0)=3/times/10/sup 4/ A/cm/sup 2/ can be achieved reproducibly.
