Abstrakt: Topological patterning of magnetic thin films has a substantial effect on domain behavior. Bubble domains located underneath a groove in patterned material display an ovoid profile with the major axis along the groove. The major axis was measured to have a diameter up to twice that along the minor axis. Measurements of the collapse field indicate that it can vary by up to 3% with changes in the groove depth, and by up to 5% with changes in the pitch of a groove array. © 2000 American Institute of Physics.
