る。Conventionally, NbTi superconducting wire of CuNi base material was used for the superconducting switch. However, the Ni content of the CuNi base material is at most about 10%, and the specific resistance of the base material is about 10 μΩ · cm.

Further, if the Ni concentration is increased in order to increase the specific resistance of the base material, there is a drawback that processing becomes difficult. This also applies to an AC superconducting wire which requires a high resistance base material.
