Successful magnet applications require fabrication of polycrystalline superconducting wires that exhibit large in-field Jc, which is limited by poor grain coupling and weak-link behavior at grain boundaries. Here we report our recent achievement in the developing Sr0.6K0.4Fe2As2 tapes with transport Jc up to 0.1 MA/cm2 at 10 T and 4.2 K.
