摘要

Y sub(1)Ba sub(2)Cu sub(3)O sub(7- delta ) (YBCO) superconducting films were grown on nonmagnetic and biaxially well textured Pt sub(0.66)Pd sub(0.34) tapes. The Pt sub(0.66)Pd sub(0.34) tapes were cube-textured by rolling and recrystallization. Good textures of Pt-Pd tapes were obtained only with certain concentrations of Pd and rolling temperatures. The buffer layers, CeO sub(2)/YSZ/CeO sub(2), were deposited by e-beam evaporations. Good textures of buffer layers were obtained only under certain conditions of oxygen partial pressure. The buffer layers with smooth surfaces were free of cracks. The YBCO films deposited on the buffer layers by a sputtering method were biaxially well-textured with 87 K of zero resistance temperature.
