摘要：

Large-size, two-dimensional YBa2Cu3O7 (YBCO) films were successfully prepared by a chemical solution-based coating pyrolysis (CP) process on 30 x 10 cm(2) R-plane sapphire substrates with a vacuum-deposited CeO2 buffer layer. The CeO2 layer was very smooth and uniform with an average roughness (R-a) of 0.48 nm by atomic force microscopic observations and highly (001)-oriented by large-area x-ray diffraction theta-2theta scans. The c-axis-oriented YBCO films were prepared by a CP process using a fluorine-free, metal acetylacetonate-based coating solution. A 30 x 10 cm(2)-rectangular c-axis-oriented YBCO film annealed in a large-diameter tube furnace demonstrated high inductive-J(c) values, for which the distribution was fairly uniform, with an average 1.0 MA cm(-2) at 77 K.
