Abstract: Apparatus for moving a single wall domain utilizing the finite mobility of the domain in a sheet of magnetic material is described. The domain is moved by changing pole patterns in a magnetically soft overlay in response to alternate slow and fast reversals of the in-plane field component aligned with the direction of domain movement.
