Yy. Tomashpol'Skii et al., 94-K superconducting yttrium barium cuprate films prepared by spray pyrolysis of methacrylate solutions, INORG MATER, 37(1), 2001, pp. 65-70
High-T-c YBa2Cu3O7 films 2-6 mum in thickness were deposited onto lanthanum
aluminate substrates by spray pyrolysis of methacrylate solutions, and the
ir properties were studied. By optimizing the deposition conditions (substr
ate material, solution concentration, and firing schedule), single-phase, n
early stoichiometric films well adherent to the substrate were obtained, wi
th T-c = 94 K and DeltaT = 9 K.
