Abstract
Ion-implanted bubble device comprises a magnetic layer in which bubble propagation paths are formed by ion-implantation. The bubble propagation path has an inside turn including a cusp of which the summit deviates toward a direction of bubble propagation with respect to a cusp center line. Such a bubble propagation path permits the ion-implanted bubble device adopting a folded minor loop organization to be realized.
