Abstract: Vortex-antivortex arrays (VAA) that are created in a type-II superconducting film by lattices of ferromagnetic dots with perpendicular anisotropy have been investigated. The highest critical current is shifted to a nonzero value of the applied field, and current-voltage characteristics show different regimes of vortex motion even in zero-applied field due to the presence of the VAA. Creep of interstitial vortices is observed at low driving forces. This flux creep is strongly field-polarity dependent.
