The London picture for the destruction of superconductivity by a current is considered. Equipotential S regions are taken as being placed periodically along the wire, and the magnetic field at the phase boundary is taken to have the critical value. From a solution of the Laplace equation for the electric potential near the contact point of two S regions a relationship between the angular aperture of the conical S region and the period of the structure is found. A numerical solution is given for the phase boundary and for the resistance at large currents. The volume of the S phase is found to be much smaller than that in the original London model. As a consequence the resistance of the wire after destruction of the uniform S state differs from that for the uniform N state by only a few percent. |
