Abstract

Magnetic bubble domain devices can be used where ion-implanted drive layers, separate from the storage layers, are used to move bubble domains in the storage layer. Figs. 1A and 1B show two devices having ion-implanted underlayer drive layers. In Fig. 1B, an ion-implanted overlayer drive layer is also provided. The storage layer can be deposited prior to ion implantation, since the storage layer is typically unimplanted and because the implantation loss density occurs mainly near the end of the projected range of the incoming particles.
