The authors report successful fabrication of superconducting YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} wire, where yttrium metal wire was used as a precursor and core. The surface of the wire was first oxidized, and was then coated by molten Ba-Cu-O. After annealing in oxygen, a superconducting layer was formed between the yttrium core and the Ba-Cu-O. The results demonstrated the feasibility of producing superconducting wire of arbitrary length with a naturally occurring thermal, chemical, and electrical insulating layer.
