Abstract: Superconducting epitaxial films of Fe-based layered arsenide, Co-dopedSrFe2As2, were grown at 700oC on mixed perovskite La, SrAl, TaO3 001single-crystal substrates by pulsed-laser deposition. Both the epitaxial filmand an 001-oriented film grown at 600oC exhibited superconducting transitionsat ~ 20 K. The zero-resistance states of the epitaxial film were sustainedunder a magnetic field H of 9 T at 9 K when H was parallel to the c-axis,while they were sustained at higher temperatures up to 10 K for H parallel tothe a-axis. This is the first demonstration of superconducting thin films ofFeAs-based new superconductors.
