Abstract
Confinement channels for magnetic bubbles are formed in a magnetic garnet layer. In the preferred embodiment, the magnetic garnet layer is etched to make it thinner than those regions not directly beneath the permalloy members. This defines channels in the garnet layer having better propagation characteristics (e.g., more garnet). This results in more reliable bubble propagation.
