Abstract
From time-resolved measurements of the flux-flow voltage detailed information can be derived about the spatial current distribution and the migration of flux domains across superconducting thin-film samples. Calculations based on the Gibbs-free-energy-barrier model achieve excellent agreement with the experimental voltage signal generated by a single flux domain. For a series of consecutive flux tubes the monopole-interaction model has to be included. In this case, the computer simulation of experimental voltage patterns reveals a damped oscillation of the number of flux quanta per domain. This number approaches an equilibrium value much smaller than the domain size in the case of a singularly existing flux tube. Flux flow in superconducting films turns out to be a convenient phenomenon for studying general properties of transient behaviour during its onset.
