Superconducting thin films of Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7-//sub x/ were fabricated using the process of plasma-assisted laser deposition. The substrate temperature was as low as 400 /sup 0/C and high-temperature post-annealing in an O/sub 2/ atmosphere was not necessary. The as-deposited films have a T/sub c/ of approx.85 K, and are oriented mostly with the c axis perpendicular to the substrate surface. The measured J/sub c/ at 80 K was 10/sup 5/ A/cm/sup 2/.
