Abstract

YBCO films on LaAlO₃ and IBAD (YSZ/Hastelloy) substrate were made by TFA-MOD (metalorganic deposition using trifluoroacetate) process. Improved coating solution resulted in high J_c at 77.3K and 0 T of 7 MA/cm² and 1.7 MA/cm² for LaAlO₃ and IBAD substrates, respectively. The magnetic field dependence of J_c at 77.3K also showed superior property: 10⁵ A/cm² at 4T (B//c-axis) for the LaAlO₃ substrate and at 3T (B//c-axis) for IBAD substrate. Furthermore, the difference in J_c between single crystal LaAlO₃ and IBAD was small up to 3T. The present results imply that TFA-MOD process is promising for the practical YBCO coated conductor process.
