Preparation of YBCO films on CeO2 buffered metallic substrates by the TFA-MOD method

Biaxially aligned YBa2Cu3O7-y, (YBCO) coated conductors on long metallic substrates are required for power applications. Recently trifluoroacetate-metal organic deposition (TFA-MOD) has been well-known as the most prospective method for the preparation of high J(c) YBCO films and it has been applied on metallic substrates. We optimized the deposition condition of the CeO2 films on MAD tapes and fabricated 10 cm class in-plane textured CeO2 buffered IBAD tapes by the PLD method. We prepared YBCO films on CeO2 buffered MAD tapes by the TFA-MOD method. The YBCO films deposited on the buffered tapes were out of plane and in-plane aligned. The J(c) value for short sample was 1.72 MA/cm(2) at 77 K, 0 T. These results suggest that the CeO2 buffered IBAD tapes are feasible for the substrate for YBCO coated superconducting wire by the TFA-MOD method. (C) 2001 Elsevier Science B.V. All rights reserved.
