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.

Abstract: Single wall domain propagation circuits include herein both magnetically soft overlays which define propagation paths along which domains move in response to reorienting in-plane fields and electrical conductors which act on magnetically hard regions in the overlay, when pulsed, to modify locally pole patterns generated by the in-plane fields. An organization in which domains are moved in a manner to eliminate unwanted effects of current pulses in those conductors on stored domain patterns is described.
