Abstract

A passive annihilator for ion-implanted contiguous-disk bubble devices has a deep cusp formed by two narrow, non-implanted regions. This annihilator has a maximum bias field margin and drive field margin, and is compatible with other components which comprise a functional ion-implanted contiguous-disk bubble device.
