Abstract

YBa₂Cu₃O_7-x film was prepared on (001) SrTiO₃ single crystal substrate by spray atomizing and coprecipitating laser chemical vapor deposition. At laser power of 101-116 W (corresponding deposition temperature was 893-942 K), a-axis-oriented YBa₂Cu₃O_7-x film was prepared, which showed an epitaxial growth mode of YBa₂Cu₃O_7-x [100]∥SrTiO₃ [001] (YBa₂Cu₃O_7-x [001]∥SrTiO₃ [100]). The a-axis-oriented YBa₂Cu₃O_7-x film had critical temperature of 75-82 K, with critical current density from 0 to 0.4 MA cm^-2. At laser power of 167-181 W (corresponding deposition temperature was 1093-1154 K), c-axis-oriented YBa₂Cu₃O_7-x film was obtained, whose epitaxial growth mode was YBa₂Cu₃O_7-x [001]∥SrTiO₃ [001] (YBa₂Cu₃O_7-x [100]∥SrTiO₃ [100]). A c-axis-oriented YBa₂Cu₃O_7-x film prepared at a deposition rate of 14 μm h^-1 showed a high critical temperature of 91 K and critical current density of 2.8 MA cm^-2.
