Vortex lattice matching effects in a washboard pinning potential induced by Co nanostripe arrays

► We furnish superconducting Nb thin films with linearly-extended uniaxial pinning nanostructures. ► An array of Co stripes is deposited by focused electron beam-induced deposition. ► Nanostructures are designed to be commensurate with the vortex lattice at small magnetic fields. ► We investigate vortex lattice matching effects by magneto-transport measurements. ► Drops in ρ(B) are observed only when the vortex lattice parameter matches the nanostructure period. ► No matching effects corresponding to the Co stripe width have been observed. ► Drops in ρ(B) are more pronounced for the vortex motion perpendicular to the Co stripes.
