Impact of magnetic environment on the impurities electronic structure. a, b The local density of states (LDOS) of V-inatom, the most skyrmion repelling impurity, as obtained when located within the collinear region (red lines in a) or close to the skyrmion core (gray lines in b). c, d Analogously for the most attracting impurity, Tc-inatom. For comparison, the LDOS of one of the closest Fe atoms to the impurity is plotted. Green corresponds to the skyrmion-case whereas blue to the ferromagnetic background. e Illustration of atom position corresponding to color code used in a–d
