Preparation of the YBCO/SmBiO3/NiO/Ni–W New Structure for Coated Conductors

A new structure basis of SmBiO3 (SBO) potential buffer layer for low-cost coated conductors fabrication methods has been introduced in this paper, and studied with XRD, SEM and AFM analyses. It is found that highly in-plane and out-of-plane oriented, dense, smooth, and crack-free SBO buffer layer has been prepared on NiO-buffered Ni-5 %W (NiW) tapes via a CSD route. YBCO epitaxial film was obtained on CSD-YBCO/CSD-SmBiO3/SOE-NiO/NiW by using...
