Abstract
We have investigated the influence of a stray field on a magnetic domain wall (DW). The depinning fields of a DW in a perpendicularly magnetized Co/Ni nanowire with partly-stacked Ni81Fe19/SiO2 islands on it was measured. The depinning field for the wire with Ni81Fe19/SiO2 was found to be higher than that for the wire without the stack, indicating that the stray field from the Ni81Fe19/SiO2 stack clearly served as an artificial pinning site for the DW. The magnetic force microscopy observation evidenced that the DW was pinned near the Ni81Fe19 stack.
