摘要：

A phenomenological model of vortex dynamics in the vicinity of the peak effect, which considers a coexistence of two vortex phases with different critical current densities, is proposed. It provides a quantitative description of the widely reported anomalous dynamic effects in terms of "contamination" and "annealing" of the vortex matter. Scanning ac Hall microscopy in the superconductor NbSe2 is used to obtain the first real-space visualization of pinning in the driven vortex lattice. The results are consistent with the proposed scenario.
