Abstract

The large-area and thick superconducting films with high crystallinity are required for most superconductivity applications. MOD process using trifluoroacetate precursors was applied to form thick YBCO films. The water vapor pressure during crystallization is a factor to control the supersaturation for the YBCO crystallization in this process. Then, the crystallization conditions such as P_H2O and heating rate were optimized to thicken the YBCO film maintaining high Jc performance. As a result, Jc depended strongly on both the water vapor pressure and the heating rate during the crystallization. Finally, a YBCO film with a high Ic value of 508A at 77K in self-field was fabricated with the YBCO film thickness of 2.7 μm under the optimized crystallization conditions.
