Contribution

It provides new experimental insights into vortex dynamics, identifying a specific moving vortex phase and associated Hall resistance phenomena in superconductors.

Findings

Large structures and peaks in Hall resistance observed

Existence of a moving vortex phase identified

Long-range inhomogeneous vortex flow characterized

Abstract

We experimentally characterize the transverse vortex motion and observed some striking features. We found large structures and peaks in the Hall resistance, which can be attributed to the long-range inhomogeneous vortex flow present in some phases of vortex dynamics. We further demonstrate the existence of a moving vortex phase between the pinned phase (peak effect) and the field induced normal state. The measurements were performed on NiZr2 based superconducting glasses.
