Abstract

The influence of the content of trifluoroacetate (TFA), in the precursor solution, on the critical current density (J^c) of YBa²Cu³O^7-x (YBCO) superconducting films was investigated. We found that a TFA/Ba ratio of 0.68 is optimal to obtain high-performance YBCO films. Using this optimal solution, we then developed an ultraviolet (UV) light soaking technique to prepare YBCO films. This resulted in the constituent elements being uniformly distributed in the films, and this then enabled enhanced J^c. The addition of water vapor during the UV soaking process decreased the content of carbon residue in the films, and further increased the J^c of the resulting YBCO films.
