Abstract
An oxide superconductive wire having practically sufficient tensile strength and superconductive properties is claimed. A first aspect of the present invention includes a first metallic layer made of a silver based alloy containing a metal selected from the group consisting of copper, antimony, tin, germanium, gallium, indium, zinc, platinum and palladium; a second metallic layer having a tensile strength higher than that of silver and fixed to the first metallic layer; and an oxide superconductor layer formed on the first metallic layer. Another aspect of the present invention provides an oxide superconductive wire having first and a second layers and an oxide superconductive wire. The first metallic layer is made of silver and oriented along crystallographic (210) plane. The second metallic layer has a tensile strength higher than that of silver and is fixed to the first metallic layer. The present invention also provides a superconductive device using each of the oxide superconductive wires. The oxide superconductor layer formed on the first metallic layer of the superconductive device is disposed on the inner side of a coiled oxide superconductive wire.
