Fig. 6: Results of growth and reversal with unipolar clock protocols, and control experiment.

a total magnetization of the ensembles subject to the different clock protocols. The timeline indicates clock time, labeled by the clock protocol. During AB clocking, the ensembles undergo growth and hence an increase in magnetization. The second phase, ab clocking, quickly reverses domains and total magnetization. The control experiment, consisting of separate A and B clock sequences, show no development of the domains. b magnetic image snapshots (experiemental XMCD-PEEM images and flatspin simulated XMCD-PEEM contrast images) of the ensembles at the specified points in time. The depicted ensembles are approximately 12.5 μm × 12.5 μm (50 × 50 pinwheel ASI, 5100 magnets). All XMCD-PEEM images are available in Fig. 7 and Supplementary Fig. 2. Videos of the experiment and simulation are provided in Supplementary Movies 1 and 2.
