Unidirectional motion of topological defects mediating continuous rotation processes.

ABSTRACT: Topological defects play a crucial role across various fields, mediating phase transitions and macroscopic behaviors as they propagate through space. Their role as robust information carriers has also generated much attention. However, controlling their motion remains challenging, especially towards achieving motion along well-defined paths, which typically require predefined structural patterning. Here, we demonstrate the tunable, unidirectional motion of topological defects in a laterally unconfined thin film. The motion of these defects-specifically magnetic dislocations-is shown to mediate the overall continuous rotation of the stripe pattern in which they are embedded. We determine the connection between the unidirectional motion of dislocations and the underlying three-dimensional (3
