Fabrication of Sm1Ba2Cu3O7 coated conductors using the co-evaporation method

We fabricated a coated conductor 7.5 m long and 9 mm wide using a biaxially textured Ni tape. The standard buffer layers, CeO2/Y SZ/CeO2, were used. A thick Sm1Ba2Cu3O7 (SBCO) film was deposited using the co-evaporation method, followed by in situ deposition of an Ag protection layer. The whole leng...

Description
Summary:We fabricated a coated conductor 7.5 m long and 9 mm wide using a biaxially textured Ni tape. The standard buffer layers, CeO2/Y SZ/CeO2, were used. A thick Sm1Ba2Cu3O7 (SBCO) film was deposited using the co-evaporation method, followed by in situ deposition of an Ag protection layer. The whole length of SBCO film was deposited in a single batch process, which took 7 h. We checked the distribution of critical currents (Ic) by I-V measurements in all the sections comprising the tape. Ic at 77 K was 90-130 A in most parts of the whole length.
