Abstract

Ag-sheathed Ba_0.6K_0.4Fe₂As₂ superconducting tapes were fabricated by a scalable rolling process with high quality precursor. At 4.2 K and 10 T, the critical current density J_c is 5.4 × 10⁴ A cm^-2. We ascribe the excellent performance to the high purity and homogeneity of the superconducting phase, and the high density and high c-axis texture of the superconducting core. Our method provides a simple way to scale up the production of long-length iron-based superconducting tapes with high J_c.
