In the fabrication of RE123 thin film conductores, oxygen annealing is generally performed after a silver protection layer is formed. It has been revealed that the interface between the silver and the RE123 layer promotes oxygen dissolution and has the effect of generating stacking defects. Tthe optimal conditions for oxygen annealing to improve critical current properties of RE123 conductors will be discussed..
