摘要

@@ We fabricated a c-axis aligned Sr<,0.6>K<,0.4>Fe<,2>As<,2> superconductor using a two-step magnetic field procedure.The effect of the magnetic fields on the structure and superconducting properties of Sr<,0.6>K<,0.4>Fe<,2>As<,2> is investigated using x-ray diffraction and magnetic measurements.The degree of orientation of the samples is about 0.39 for the c axis and 0.51 for ab-plane orientation, as evaluated from the Lotgering factor of x-ray diffraction.This technology may be useful in a variety of potential applications, including preparing iron-based superconducting bulks and wires with high critical currents.
