Abstract
Metal organic deposition (MOD) process of YBa2Cu3O7−y (YBCO) using metal trifluoro acetate (TFA) precursors is thought to be promising since YBCO films with high Jc can be fabricated by this process inexpensively. However it is difficult to maintain high Jc throughout long tapes.We have improved Ic values and longitudinal Ic distribution for a long coated conductor tape by the advanced TFA-MOD method.It was clarified that a humid atmosphere degraded as-coated films. The Ba-poor composition precursor from the 1:2:3 cationic ratio improved Jc/Ic significantly. As a result, a 86m long coated conductor was obtained with Ic values higher than 200A/cm-w throughout the tape except for one small region. Almost of the tape has as high Ic as 300A/cm-w and the end-to-end Ic×L value was 14000Am (Ic=250A, L=56m).
