Commensurability effects induced by a periodic array of nanoscale anti-dots in Nb superconductor
Commensurability effects induced by a periodic array of nanoscale anti-dots in Nb superconductor
We study the interactions of the vortex lattice with a periodic square array of holes in a superconducting Nb film using magnetic and resistive measurements. Three different temperature regions have been observed. They are governed by interplay between vortex–vortex interactions and pinning by holes. At low temperatures flux jumps suppress the commensurability anomalies. In all measurements a peak has been observed close to commensurate states 5–7. The Cole–Cole plot reveals significant changes in the flux penetration mechanism at this point.

Abstract
We study the interactions of the vortex lattice with a periodic square array of holes in a superconducting Nb film using magnetic and resistive measurements. Three different temperature regions have been observed. They are governed by interplay between vortex–vortex interactions and pinning by holes. At low temperatures flux jumps suppress the commensurability anomalies. In all measurements a peak has been observed close to commensurate states 5–7. The Cole–Cole plot reveals significant changes in the flux penetration mechanism at this point.
