Among various chemical manufacturing methods for REBa₂Cu₃O_y (RE123) superconducting thin films, the fluorine-free (FF)-MOD method is the most suitable for mass production because biaxially oriented thin films can be grown in a short time by a relatively simple solid-state reaction. In our study, we have optimized the preparation composition of the raw material solution and sintering conditions for the improvement of critical current (I_c) in the preparation of RE123 thin films on the tape-like metal clad (CeO₂/YSZ/Y₂O₃/Ni/Cu/SUS) substrate with a biaxially oriented intermediate layer that can be lengthened using the FF-MOD method.
