Title: Superconductive wire
Inventor: ICHIMARU OSAMU
IPC: H01B12/02
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To increase an upper critical magnetic field and critical current density of a superconducting wire material containing an artificial pin so as to have high performance by introducing a superconductor having a larger upper critical magnetic field than a superconducting filament as the artificial pin. SOLUTION: A superconductor having an upper critical magnetic field Bc2 larger than a superconducting filament of NbTi or the like, for example Nb3 Sn is introduced as an artificial pin. Elemental pinning force fp of Nb3 Sn pin is proportional to free energy in a superconducting state of both of NbTi and Nb3 Sn. The elemental pinning force fp is proportional to the difference δBc2=12T between the upper critical magnetic field Bc2=23T of Nb3 Sn and the upper critical magnetic field Bc2=11T of NbTi. When an outside magnetic field B and pin density (p) are made constant, since critical current density Jc of a wire material is proportional to the elemental pinning force fp, by replacing NbTi pin with Nb3 Sn, the critical current density Jc of the wire material can be increased twice.
