Abstract

Although high critical current density (J_c) YBCO can be deposited on rolling assisted biaxially-textured substrates (RA-BITS) 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 1.8×10⁶ A/cm² at 77 K has been obtained on this Yb₂O₃/Y₂O₃/Ni alternative RABiTS architecture.
