The pinning properties of magnetic vortex domain walls were experimentally investigated in patterned nanowires with artificial constrictions. Domain walls were nucleated and depinned by applied magnetic fields and observed with magnetic force microscopy. It was found that the pinning strength is dependent on the chirality of the vortex wall. Micromagnetic simulations confirm these results and reveal the energy potential of the pinned domain wall, including the width of the pinning site.
