抄録
The critical current density (Jc) and irreversibility field (Birr) of epitaxial SmBa2Cu3O7−x (SmBCO) films are reported. The Birr and Jc of these films deposited on MgO(100) substrates by pulsed-laser deposition depend critically on the substrate temperature. The use of a thin SmBCO seed layer grown at a high substrate temperature enabled us to obtain fully c-axis-oriented SmBCO films at relatively low temperatures, resulting in a high Jc of 1.7×105 A/cm2 of B||c at 5 T and 77 K. This value is as high as that of the optimized NbTi superconducting wires achieved at 5 T and 4.2 K.
