xy-slices of the experimentally measured 3D magnetic field at t= 132 nm showing the surface skyrmions. The colors display the orientation of the experimentally measured 3D vector field as mapped by the 3D color map outlined by the black rectangle in between (d,f) whereas the arrows length represents the magnitude of the in-plane projection of the 3D magnetic field. The spin texture is outlined by a solid dark grey rectangle. The right-hand-side inset plots the magnetic field in thexz- andyz-planes intersecting the antiBP indicated by a solid green square in (d).
