a Schematic of the MFM scanning configuration. Creation of Q = 0 skyrmion bags (b), Q = 1 skyrmion bags (c), and Q = 2 skyrmion bags (d) induced by several MFM tip scans. e Conversion of Q = 1 skyrmion bags to Q = 0 skyrmion bags after the second scan. f Conversion of Q = 2 skyrmion bags to Q = 1 skyrmion bags after the fifth scan. Low-moment MESP-LM-V2 tips (Bruker) with stray fields of around 200 Oe (at the apex of the tips) were used in b–f. The number of the scan is marked above the disks and the color bar represents the MFM phase shift.
