Among the various preparation methods of RE123 thin films, fluorine-free metal organic decomposition (FF-MOD) is expected to be a low-cost and mass production method because thin films with homogeneous and flat surfaces can be prepared by a short sintering time using simple sintering devices under ambient pressure. In recent studies, it was found that Tb-doping to Dy123 melt-textured bulks resulted in the formation of BaTbO₃ in the bulks and enhanced critical current density(J_c).In this study, we will report the microstructures and critical current properties of Y123 thin films doped with Tb of different concentration.
