Abstract

Metalorganic deposition process using trifluoroacetate (TFA-MOD) processed YBCO film on LaAlO₃ and IBAD (YSZ/Hastelloy) substrate exhibited high critical current density, J_c, at 77.3 K. The obtained J_c values at 0 T were 7 and 1.7 MA/cm² for LaAlO₃ and CeO₂ buffered IBAD, respectively. High J_c values over 10⁵ A/cm² were maintained up to 4 T (B∥c-axis) for the LaAlO₃ substrate and up to 3 T (B∥c-axis) for the CeO₂ buffered IBAD substrate. These results imply that TFA-MOD with simple fabrication process is very promising for the practical YBCO coated conductor.
