抄録

We have fabricated Ba0.6Na0.4Fe2As2 round wires using powder-in-tube method and hot isostatic pressing, and evaluated their critical current density (Jc). Transport Jc at 4.2 K of the wire reached 76 kA/cm2 and 24 kA/cm2 at self-field and 100 kOe, respectively. The weak magnetic field dependence of Jc in Ba0.6Na0.4Fe2As2 demonstrates the good potential of this material as superconducting wires. Detailed characterizations of the wires using magneto-optical imaging, X-ray diffraction measurements, and compositional mapping by energy-dispersive X-ray spectroscopy analyses are also presented.
