Fabrication and Characterization of YBa₂Cu₃O_y Superconducting Nanowires

Ordered YBa₂Cu₃O_y nanowires have been fabricated by filling YBa₂Cu₃O_y melting liquid into the pores of the anodized alumina templates. X-ray powder diffraction proves that YBa₂Cu₃O_y nanowires crystallized in the Y-123 structure. The temperature dependence of ac susceptibility indicates a superconducting transition at 91K for the YBa₂Cu₃O_y nanowire array.
