Enhancements of superconducting properties were observed in FeSe wires using a quenching technique. Zero resistivity was achieved at about 10 K in quenched wires, which is about 2 K higher than that of polycrystalline FeSe bulk. Furthermore, transport J c of quenched wires showed three times higher than that of furnace-cooled wires. In contrast, the quenched polycrystalline FeSe bulks did not show the enhancement of T c. The quenching technique is greatly promising for fabricating FeSe wires with high T c and high J c, and quenched FeSe wires have high potential for superconducting wire applications.
