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.

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.File in questo prodotto:
