Abstract
A magnetic device comprising at least one thin domain layer of a magnetizable material which has an easy axis of magnetization which is substantially normal to the surface of the layer and in which magnetic domains are propagated under the influence of a bipolar current, for example an alternating current, by a pattern of electrically conductive material with which the layer is provided. Elements are furthermore present which cause an asymmetry force and thus determine the direction in which the domains are propagated. The electrically conductive material and the elements are present in a single pattern which is constructed from at least a layer of magnetic material.
