Fig. 4: Distance dependent anisotropic exchange parameters.

Antisymmetric exchange parameters \({D}_{ij}=\sqrt{{D}_{{x}_{ij}}^{2}+{D}_{{y}_{ij}}^{2}+{D}_{{z}_{ij}}^{2}}\) as a function of neighboring distance R_ij for a, b Fe₃GeTe₂, e, f Fe₄GeTe₂ and i–n Fe₅GeTe₂ monolayer, obtained using GGA+DMFT. c, d, g, h, o, p The first neighbor DM interactions between different ith and jth pairs. The D_ij values are multiplied by the corresponding coordination numbers.
