ABSTRACT:
A magnetic bubble device in which ions are implanted, under different conditions, in at least two kinds of regions of a magnetic thin film serving as a medium for propagation of a magnetic bubble. In this manner, the operating margins of magnetic bubble stable operation regions of respective functional parts of the device are made nearly equal, thereby providing for improved operating margin of the device as a whole.
