A thin Y-Ba-Cu-O film was formed by the organometallic chemical vapor deposition (OMCVD) method. The substrates used were (100) and (110) SrTiO/sub 3/. After forming Y-Ba-Cu-O at 800 /sup 0/C, it was cooled at a rate of 100 /sup 0/C/min in O/sub 2/ under 1 atm. This film was c-axis oriented, with its (001) surface grown in parallel to the (100) surface of SrTiO/sub 3/ and T/sub c/ = 88 K. The (110) surface of Y-Ba-Cu-O was grown in parallel to the substrate crystal and T/sub c/ = 84 K on the (110) surface of SrTiO/sub 3/. After forming, these films were quenched in air from 800 /sup 0/C to room temperature. The change in resistance of the quenched sample with temperature was metallic, T/sub onset/ = 75 K, and T/sub c/ = 60 K.
