抄録

We have fabricated Ba_0.6Na_0.4Fe₂As₂ round wires using powder-in-tube method and hot isostatic pressing, and evaluated their critical current density (J_c). Transport J_c 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 J_c in Ba_0.6Na_0.4Fe₂As₂ 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.
