Vortex matching effect in engineered thin films of NbN

We report robust vortex matching effects in antidot arrays fabricated on thin films of NbN. The near absence of hysteresis between field sweep directions indicates a negligible residual pinning in the host thin films. Owing to the very small coherence length of NbN thin films (ξ<5 nm), the observations suggest the possibility of probing physics of vortices at true nanometer length scales in suitably fabricated structures.
