Abstract
The undulating longitudinal edge of a continuous elongated structure of magnetic material forms a bubble domain propagation path for implementing the continuous movement of magnetic bubble domains under the control of a reorienting in-plane magnetic field. The domains propagate along the periphery of the undulating layer, with the periphery preferably taking the form of linked outwardly convex semi-circles. The structure can be comprised of a magnetically soft material, such as permalloy, or be an implanted region in the magnetic material which supports the bubble domains.
