A multiple-field coupled resistive transition model for superconducting Nb3Sn

A multiple-field coupled resistive transition model for superconducting Nb3Sn

A study on the superconducting transition width as functions of the applied magnetic field and strain is performed in superconducting Nb3Sn. A quantitative, yet universal phenomenological resistivity model is proposed. The numerical simulation by the proposed model shows predicted resistive transiti...
