Effects of film thickness on the electrical properties of YBa2Cu3O7−δ films grown on a multilayer-coated Hastelloy C276 tape by laser CVD

YBa2Cu3O7−δ (YBCO) films with thicknesses from 0.10 to 0.73 μm were prepared on a multilayer-coated Hastelloy C276 tape by laser chemical vapor deposition (laser CVD) using a single liquid precursor. c-axis-oriented YBCO films with an in-plane orientation were obtained. With increasing film thickness from 0.10 to 0.73 μm, the a-axis orientation slightly increased, the in-plane and out-of-plane orientations improved, and the composition approached the stoichiometric ratio. The critical temperature and critical current density for the 0.73-μm-thick YBCO film were 90 K and 1.5 MA cm−2, respectively.
