An ion-implanted contiguous-disk bubble device

This invention relates to an ion-implanted contiguous-disk bubble device including a major loop (12), folded minor loops (18A, 18B, 18C) and transfer elements (28A, 28B, 28C) positioned between the major loop (12) and the folded ends (22A, 22B, 22C) of the minor loops. In a preferred embodiment, the...

More Information
Summary:This invention relates to an ion-implanted contiguous-disk bubble device including a major loop (12), folded minor loops (18A, 18B, 18C) and transfer elements (28A, 28B, 28C) positioned between the major loop (12) and the folded ends (22A, 22B, 22C) of the minor loops. In a preferred embodiment, the transfer element (28A) has a merge portion (32A) adjacent and in spaced relation to the folded end (22A) of the minor loop (18A). In a second embodiment the transfer element is connected directly to the folded end portion of the minor loop. Preferably the periodicity in the major loop is about times the periodicity of the minor loop.
