摘要：

Superconductor film of YBa2Cu3O7-delta having high-J(c) values was formed on a CeO2/YSZ buffered metal tape by the metal-organic deposition using trifluoroacetates (TFA-MOD) method. Transmission electron microscopy (TEM) confirmed the presence of microstructures of multi-layered structure of YBCO/CeO2/YSZ/Ni-based alloy. The thickness of each thin film YBCO, CeO2 and YSZ, was estimated to be 0.2, 0.5 and 1.3 mum, respectively. Both the film of YSZ on polycrystalline and the film of CeO2 on the YSZ film were composed of columnar grains aligned 10 0) direction. The columnar structure of the CeO2 film was strongly correlated to that of the structure of YSZ film. While highly oriented YBCO film was formed on the CeO2 film, it was not dense and had a rough surface. TEM-EDS revealed copper oxide in the film of YBCO and secondary phase produced from YBCO and CeO2 (BaCeO3) between the two layers. (C) 2002 Elsevier Science B.V. All rights reserved.
