Abstract: The movement of single wall domains in an internal layer of a film of magnetic material permits operation unencumbered by surface defects or interactions with substrates on which the film is formed for bias fields over a range which is large compared to the range of bias fields characteristic of films in which single wall domains extend from surface to surface.

Abstract: Single wall domains are moved in a layer of a host magnetic material in response to magnetic poles generated in channel defining elements in response to a magnetic field reorienting in the plane of the layer in what is called a ''''field access'''' mode of operation. Domains are transferred herein between channels, so defined, by the in-plane field when the originating and receiving positions for a domain at each transfer location are encompassed by a conductor loop which, when pulsed, defines a magnetic fence about the positions.

Abstract: An arrangement for moving single-wall domains is described which employs an in-plane magnetic field to incline a domain from alignment with an axis of preferred magnetization of the material in which it is moved. As the in-plane field reorients, the orientation of the inclination changes. The changing domain inclination is converted to domain translation along an axis defined by a magnetic overlay in which a permanent magnetic pattern is printed.
