Extended Data Fig. 3

The time-resolved MOKE dynamics are shown as a function of the vertical position within the magnetic region, along the red dashed line. The colour of the traces corresponds to the positions indicated by the corresponding coloured circles in the sample picture. Inset shows the peak of the dynamics (at 11 ps) as a function of the y position (across the sample width). The signal drops as we get close to the edges because the probe no longer fully overlaps the magnet (the probe width is about 1.5 µm (FWHM), and the sample width is 4 µm. The dynamics are extremely similar across the surface of the sample. Experiments along the length of the magnet (x direction) also showed no major differences.
