Metalorganic chemical vapor deposition (MOCVD) of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} films on (100) SrTiO{sub 3} was performed in a high-speed rotating disk reactor. Metal {beta}-diketonates were used as source materials. Energy dispersive spectroscopy analysis showed as-grown and post-annealed samples to have a composition matching that of superconducting thin-film standards. X-ray data showed the annealed films to be highly oriented with the {ital c} axis perpendicular to the substrate. The best films exhibited an onset temperature of 90 K and zero resistance at 88 K. The width of the superconductive transition ({lt}2 K) is the best value thus far reported for 123 films grown in a commercially available MOCVD system.
