  We report on the controllable pinning of domain walls in stripes with
perpendicular magnetic anisotropy by magnetostatic coupling to magnetic
vortices in disks located above the stripe. Pinning mechanisms and depinning
fields are reported. This novel pinning strategy, which can be realized by
current nanofabrication techniques, opens up new possibilities for the
non-destructive control of domain wall mobility in domain wall based spintronic
devices.
