Biaxially aligned YBa2Cu3O7-y, (YBCO) coated conductors on long metallic su
bstrates are required for power applications. Recently trifluoroacetate-met
al 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 buffer
ed IBAD tapes by the PLD method. We prepared YBCO films on CeO2 buffered MA
D tapes by the TFA-MOD method. The YBCO films deposited on the buffered tap
es 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 buffere
d 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 rese
