Bi2Sr2CaCu2Ox superconducting films containing minor amounts of Bi2Sr2Ca2Cu3Ox were prepared by spray pyrolysis of methacrylate solutions on LaAlO3 substrates. The best superconducting properties (Tc ? 80 K, ΔTc ? 10 K) were shown by the films annealed at 850°C, which consisted mainly of platelike crystallites with a high degree of [001] orientation. The composition, content, and morphology of the calcium strontium cuprates and oxides present as impurity phases were found to correlate with the annealing temperature and film thickness.
