History and Future Prospect of Practical Superconducting Material Developments

Abstract

Practical superconducting wires and tapes have been developed after a discovery of superconductivity in 1911. Nowadays, many “practical” superconducting wires and tapes are available commercially and used for various applications. Most of them are multifilamentary wires with stabilizer. The present status of practical superconducting wires and tapes are introduced with short histories.
