Abstract
The present invention provides a high-temperature oxide superconductors, which comprises an oxide expressed as (Bi.sub.1-xA.sub.x)--B--C--Cu oxide (where, A is Sb and/or AS; B and C are elements different from each other, each being one or more elements selected from the group consisting of Be, Mg, Ca, Sr and Ba; and x is characterized by 0.ltoreq.x.ltoreq.1). According to the present invention, it is possible to manufacture a high-temperature oxide superconductor having a transition temperature of over 100 K and not containg a rare-earth element at all, and to manufacture an excellent superconductor in reliability and stability easilier than doing conventional superconductors such as Y--Ba type ones.
