Effect of deposition temperature on the orientation and electrical properties of YBa2Cu3O7−δ films prepared by laser CVD using liquid-source evaporation

YBa2Cu3O7−δ (YBCO) films were prepared on a multilayer-coated Hastelloy C276 tape by laser chemical vapour deposition using liquid-source evaporation. The orientation of the YBCO films changed from a-axis to c-axis when the deposition temperature was increased from 1010 K to 1090 K. The c-axis-oriented YBCO film prepared at 1046 K exhibited critical temperature of 92 K and critical current density of 1.7 MA cm−2 at a deposition rate of 13 μm h−1.
