It is difficult to make wires as thin as alloy-based superconducting materials such as i. Conventionally known methods for manufacturing such compound-based superconducting wires include (1) bronze method, (2) in-situ method, (2) powder metallurgy (PM) method, (2) composite processing method, and jelly roll method. Among compound-based superconducting materials, Nb3At-based superconducting materials are said to have good critical current density and strain resistance in high magnetic fields. A manufacturing method called the jelly roll method is currently said to be the closest to practical use of such Nb3At-based superconducting materials. However, with this jelly roll method, the wire drawability was still insufficient, and it was difficult to make wires with multiple cores or thin wires.
