Abstract: Single wall domains are moved in a slice of magnetic material by magnetically soft overlay patterns on both surfaces of the slice. The overlays are shaped alike and are offset one from the other along the axis of domain movement so that each provides pole patterns to attract a domain to the same consecutive positions as a magnetic field reorients in the plane of the slice.
