Extended Data Fig. 5: Further analysis of PEEM measurement results of skyrmion bags with 7 skyrmions in a commensurate superlattice at 13.2° twist angle.

a, Electric field distribution. The out-of-plane component is illustrated using the color plot. b, Skyrmion number density of the electric field. Integration of the skyrmion number density yields the total skyrmion number. For the total bags the integrated area is given by the enclosed space inside the green dashed lines. The skyrmion cluster only counts the skyrmions inside the bag, which means that the skyrmion number density is integrated within the area surrounded by the dashed red lines. In this measurement, three out of seven skyrmion bags of the observed superlattice have the correct skyrmion numbers of \({S}_{\mathrm{bag}}=6\) and \({S}_{\mathrm{cluster}}=7\). The center super-cell is surrounded by black dashed lines.
