a Top view of the two Co/C60 adsorption geometries. b Top view of the Co/Gaq3 slab, alongside with the frame of reference highlighting the easy axis obtained from the DFT calculation. The Co atoms are in gray. The atoms of the molecules are respectively represented by brown (C), red (O), cyan (N), pink (H), and green (Ga) spheres (c) EMCA as a function of the in-plane magnetization angle θ for two Co/C60 and one Co/Gaq3 slabs. The results are shifted so that E(θ = 0o) = 0 meV. d A schematic representation of the correlation radius rC. The arrows on the different figures indicate the local anisotropy axes.
