Oriented-Y-Ba-Cu-O thin films with thicknesses between 0.6 and 0.7 ..mu..m have been deposited on magnesium oxide substrates by the flash evaporation method. The deposition was made by dropping powders of sintered Y/sub 1/ Ba/sub 2/ Cu/sub 3/ O/sub 7/minus//ital x// onto a resistively heated tungsten boat. The as-deposited films were then annealed at 930 /degree/C in oxygen for 60 min. Annealed films were superconductors above 77 K and x-ray diffraction showed a preferred /ital c/-axis orientation. Increasing the annealing temperature to 945 /degree/C improved the texture of the films and the transition temperature of the superconductivity.
