Abstract

We have reported high-Jc Sm1+xBa2-xCu 3Oy, (SmBCO) films on single crystal MgO prepared by pulsed laser deposition (PLD). In this study, we fabricate SmBCO films on metallic substrates using low temperature growth (LTG) technique, to investigate the availability of the LTG technique for coated conductors. The LTG-SmBCO films are deposited on PLD - CeO2/IBAD - YSZ/Hastelloy tapes. The critical current density (Jc) is 4.7 MA/cm2 (77 K, B//c, B = 0 T) and 0.23 MA/cm2 (77 K, B//c, B = 5 T). Furthermore, at 65 K and B = 17 T, the Jc of LTG-SmBCO film (B//c) reaches 0.03 MA/cm 2. These values are higher than those of conventional PLD-YBCO and PLD-SmBCO films. From these results, we suggest that the LTG is an effective technique for improving the magnetic field dependence of Jc of coated conductors.
