Collective and plastic vortex motion in superconductors at high flux densities.

Type of article: Article

Summary

Scanning tunnelling microscopy has the potential to resolve individual vortices at much higher flux densities. The authors find that, in the presence of strongly pinning line defects, the vortex lattice remains pinned until the number of vortices is about twice that of the defects, at which point plastic creep commences. But in the presence of weak intrinsic point disorder, the vortices creep coherently along one of the principle axes of the vortex lattice, where they exhibit striking and unanticipated velocity modulations that appear to be related to the lattice periodicity.
