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.
