Extended Data Fig. 6: Vortex domain wall displacement within the bulk of the microdisc.
From: Time-resolved imaging of three-dimensional nanoscale magnetization dynamics
Displacement of the vortex domain walls with negative vorticity (a, blue in left-hand panel and Fig. 4) and positive vorticity (b, red in left-hand panel and Fig. 4) in the direction perpendicular to the long axis of the domain wall (indicated by grey arrows in the left-hand panel) as a function of time for different heights within the structure. The oscillatory behaviour is clearest for both vortices at a height of 46 nm and is less clear at the top. When comparing the motion of the two vortex domain walls, the oscillations appear to be consistently out of phase through the height of the sample. Scale bar is 1 μm.
