摘要：

Although high critical current density (J(c)) YBCO can be deposited on rolling assisted biaxially-textured substrates (RABiTS) with the YSZ/CeO2/Ni architecture, improvement in uniformity is needed due to the presence of two-component YBCO epitaxy and cracking in the CeO2 buffer. We have determined that Yb2O3 is an excellent buffer material that provides a single-component YBCO epitaxy. In addition, crack-free epitaxial Y2O3 can be consistently deposited onto textured Ni substrates. High quality YBCO films have been deposited, and J(c) as high as 1.8 x 10(6) A/cm(2) at 77 K has been obtained on this Yb2O3/Y2O3/Ni: alternative RABiTS architecture.
