Abstract

The critical current density, Jc, of metal-organic deposition process using trifluoroacetates (TFA-MOD) based YBCO films was measured between 20 K and 77 K in magnetic fields up to 9.5 T as a function of the field direction. C-axis oriented YBCO films was deposited on LaAlO₃ single crystalline substrates and also on CeO₂ buffered IBAD (YSZ/Hastelloy) substrates by TFA-MOD method. The obtained Jc values at 77 K and 0 T were 7 and 1.7 MA/cm² for LaAlO₃ and IBAD substrates, respectively. High Jc 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. And the dependences on temperature and angular of the Jc at various external magnetic fields for some different thicknesses YBCO films was reported.
