(a) Top-view of a simulated skyrmion structure at its equilibrium state when B_z=48 mT. Scale bar, 200 nm. (b) Pulse profile used for the simulation, which is slightly different from the actual profile used in experiments due to impedance mismatching in experiments. (c) Time-dependent skyrmion size variation when we consider SOT-only, Oersted field-only and SOT and Oersted field simultaneously. (d) Experimentally measured (left-axis) and computed (right-axis) skyrmion diameter as a function of pulse delay time. (e) Time-dependent skyrmion travel distance of SOT-only, Oersted field-only and SOT and Oersted field models. (f) Experimentally measured (left-axis) and computed (right-axis) skyrmion travel distance as a function of pulse delay time. Note that y-axis scales are different between the experiment and computational model in d,f. Error bars in d,f indicate the spatial resolution of beamline, ∼25 nm.
