We report a combined experimental and theoretical study on the influence of slanted nanostripe edges on the magnetic domain wall (DW) dynamics in permalloy nanostripes. The DWs show a significantly different behavior in the same sample depending on the magnetization configuration in the DW. We explain these characteristics via a difference of the stray field generated by the out-of-plane magnetization inside the DW in the nanostripe edge region during DW motion.
