Vortex dynamics in the region of charge imbalance

The nature of vortex flows in the nonequilibrium region arising in the vicinity of phase-slip lines at the S-N boundary are investigated experimentally. It is shown that vortices continue to move when charge imbalance appears in a film that is in a dynamic mixed state. The vortex dynamics in this case is determined by the interaction of the vortices with only the superconducting component of the current. This statement is supported by a study of the dynamic mixed state in the nonequilibrium region near the S-N boundary.
