Abstract
We report simulations of a frustrated odd-numbered macrospin ring system, with full point dipolar interactions, driven by a rotating uniform applied magnetic field of constant magnitude. The system is designed with equally-spaced radially-aligned macrospins, which must carry a frustrated soliton defect in its ground state. It is shown how correctly tuning the applied field magnitude can allow for non-trivial unidirectional propagation of the soliton, the required directional pressure acquired via the curvature of the ring. Furthermore, the system, which may be employed as a multiple rotation counter, is tested for robustness against quenched disorder as would be present in an experimental realization.
