Superconducting thin films of Y-Ba-Cu-O oxide have been prepared on (100) MgO substrates by flash evaporation in oxygen plasma. The as-grown films deposited at substrate temperatures from 385 to 550 /degree/C show superconducting properties with a critical temperature /ital T//sub /ital c// of about 90 K. Transmission electron diffraction indicates that a film deposited at below 430 /degree/C has both amorphous and polycrystalline regions, and that a film at above 430 /degree/C is polycrystalline.
