The results of the experimental study of the interaction of cylindrical magnetic domains (CMDs) with a topological potential barrier in the form of an etching step with different angles of the slope are presented. A technique for the determination of the barrier field H b is proposed; its value as a function of the step slope angle is found for a concrete film. On the basis of the obtained results, some possible devices based on the topological barriers in CMDs containing garnet films are proposed.
