摘要：

We report the realization of grain alignment in Sn-added Sr1-xKxFe2As2 superconducting tapes with Fe sheath prepared by ex-situ powder-in-tube method. At 4.2 K, high transport critical current densities J(c) of 2.5 x 10(4) A/cm(2) (I-c = 180 A) in self-field and 3.5 x 10(3) A/cm(2) (I-c = 25.5 A) in 10 T have been measured. These values are the highest ever reported so far for Fe-based superconducting wires and tapes. We believe the superior J(c) in our tape samples are due to well textured grains and strengthened intergrain coupling achieved by Sn addition. Our results demonstrated an encouraging prospect for application of iron based superconductors. (C) 2011 American Institute of Physics. [doi:10.1063/1.3671109]
