Growth of Biaxially-Textured La2Zr2O7 and Zr-doped CeO2 on Cold-Rolled Ni-W Substrate by CSD

Abstract

The growth of oriented buffer layers by chemical solution deposition (CSD) on cube-textured Ni-based substrate is a key point for the development of low-cost YBa2Cu3O7-x (YBCO) coated conductor. Among the suitable compounds, La2Zr2O7 (LZO) and CeO2 are of particular interest as they enabled an all-chemical route for the fabrication of YBCO coated conductor. It has been recently shown that CSD films can be grown by direct precurson solution deposition on as-rolled, i.e., without cube orientation, metallic substrate. In particular, LZO film with biaxially 001 texture has been successfully grown on either pure copper or Ni-W alloy substrate. In the present contribution, the deposition either L..
