The preparation of high T/sub c/ superconducting thin films of Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7-//sub delta/ on (100) single crystals of MgO, ZrO/sub 2/ with 9% Y/sub 2/O/sub 3/ (yttria stabilized zirconia, or YSZ), and SrTiO/sub 3/ using a simple spray deposition technique is described. Typical film growth procedure involves (a) the spraying of a stoichiometric solution of the nitrate precursors on the heated substrate (180 /sup 0/C), (b) prebaking in air of the sprayed film (20 min at 500 /sup 0/C), and (c) oven annealing of the film under flowing O/sub 2/ (900--950 /sup 0/C followed by slow cooling to 200 /sup 0/C in about 3 h). X-ray diffraction analysis of the films after each of the growing steps mentioned above shows primarily the presence of crystalline phases of the nitrates, the oxides, and the orthorhombic superconducting phase, respectively. Resistivity versus temperature measurements show that the onset and completion of the superconductive transition occur at 92 and 87 K, respectively, in films on YSZ substrate; at 95 and 80 K, respectively, in films on SrTiO/sub 3/ substrate; and at 82 and 77 K, respectively, in films on MgO substrate.
