Thin films of the high /ital T//sub /ital c// superconducting Y-Ba-Cu metal oxide have been prepared for the first time by plasma-assisted organometallic chemical vapor deposition using ..beta..-diketonate chelates of Y, Ba, and Cu, Y(C/sub 11/H/sub 19/O/sub 2/)/sub 3/, Ba(C/sub 11/H/sub 19/O/sub 2/)/sub 2/, and Cu(C/sub 11/H/sub 19/O/sub 2/)/sub 2/ as starting materials, followed by post-annealing under a reduced pressure of oxygen stream. X-ray diffraction spectra indicate that the films deposited on the yttria-stabilized zirconia (YSZ) substrate have a significant preferential orientation of the crystallite /ital c/ axis being perpendicular to the substrate surface. Four-probe resistivity measurements reveal the temperature of the onset of superconductivity at 91.6 K and zero resistance by 78.5 K.
