Abstract

The voltage shift RfIc with respect to the flux flow ohmic behavior of the current–voltage characteristic in type II superconductors is ascribed to the irreversible processes occurring when a vortex crosses defects. We include irreversible effects of the vortices–defects interaction into an effective law of motion. The obtained current–voltage characteristic at finite temperature is in agreement with experimental data.
