(a) Stray field map measured using NV magnetometry on a \({\hbox {NdMn}_2\hbox {Ge}_2}\) disk lamella, at a lift height of 300 nm. These stray field maps directly reflect the ferromagnetic moment of the canted antiferromagnetic sublattice. (b) A stray field map calculated from the disk lamella simulation at a lift height of 300 nm. (c) The black line profile shows the strength of the stray field for three skyrmion bubbles from the NV stray field map. A line profile for three skyrmion bubbles from simulations is plotted in red. Also plotted is the line profile (blue) calculated (using Eq. 2) from the simulation stray field data when accounting for dead layers of material and a different NV height.
