Abstract
By use of a simple semiphenomenological argument, Sherman and the author showed that in nearly pure superconductors (mean free path large compared with the core radius) at low temperatures, the transport current flows directly through the core of a vortex line without backflow. Expressions they derived for the flux-flow resistivity and Hall angle are nearly identical with those derived later by Larkin and Ovchinnikov (resistivity) and by Kopnin and Kravtsov (Hall angle) using Green's-function methods except for a numerical factor of 4/3. It is shown that this factor comes from a difference in relaxation time between the vortex core and the normal metal.
