  • We have studied magnetic domain structure in (YSmLuCa)3(FeGe) 5O12 garnet thin film by using magnetic force microscopy (MFM). Domain wall contrast of bubble domains has been revealed using Permalloy-Fe double-layer thin-film tips. We have also observed that nanometer scale deformations of the surface disturb a magnetic bubble structure by introducing stripe domains. MFM images have shown that stripe domains pin their domain walls to surface scratches. The domains can change their location with respect to a scratch by switching a domain wall pinned to a scratch. © 1995 American Institute of Physics.
