Thin films of the high-temperature superconductor DyBa/sub 2/Cu/sub 3/O/sub 7-//sub x/ have been grown on SrTiO/sub 3/ substrates using molecular beam epitaxy techniques. Reflection high-energy electron diffraction patterns observed during deposition indicate incomplete oxidation of copper and growth of oriented metallic copper microcrystals in a matrix of amorphous barium and dysprosium oxides. After post-growth anneal the films exhibited sharp superconducting transitions with zero resistance observed as high as 89 K and critical current densities of 4.8 x 10/sup 5/ A/cm/sup 2/ at 4.2 K and 3.9 x 10/sup 4/ A/cm/sup 2/ at 77 K.
