摘要
Thin-textured YBa2Cu3O(y)(Ag) films were prepared by a new CVD process consisting of aerosol deposition and low temperature annealing, both operations not exceeding 600-degrees-C. MgO and SrTiO3 single crystals were used as substrates. The stoichiometry of the prepared films was not ideal 1-2-3, having the atomic quotient of copper always lower than 3. For an unoptimized preparation process, the onset temperatures were around 80 K and the zero resistance T(c) values around 70 K. Properties of samples obtained by low-temperature annealing are compared with those obtained by high temperature annealing. "Cleaning" effect of vacuum-annealing upon removing the nitrate and hydroxide groups from the prepared films is supposed.
