摘要：

Superconducting FeSe in the form of wires and tapes were successfully fabricated using a novel gas diffusion procedure. Structural analysis by means of x-ray diffraction shows that the main phase of tetragonal PbO-type FeSe was obtained by this synthesis method. The zero resistivity transition temperature of the FeSe was confirmed to be 9.3 K. A critical current density as high as 137 A cm(-2) (4 K, self-field) was observed. The results suggest that the diffusion procedure is promising in preparing high-quality FeSe wires and tapes.
