• . Depending on the sign of the zero field splitting parameter, D, in 1 at 3 K the iron(III) ions will be in a ground state that could be either |±5/2> or |±1/2>. If the relaxation between the positive and negative spin states becomes slow enough, the relaxation between the different MS states may still be

• are almost fully transmitting. For the majority spins, we notice the dzx and dyz orbital nature of wavefunctions on the V adatoms contacting C60 (z chosen perpendicular to the surface). This is in accordance with the Mulliken population analysis of the majority spin states of the V tip and adatoms

• spin states, while the 5d and the majority states remain nearly unaffected. This makes the distribution of the minority spin 3d states in the vicinity of the Fermi level a decisive factor for the evolution of the stability of the structures with composition. When replacing Fe by Co, the additional d

• electrons of Co necessarily fill up the minority channel, because the majority spin states are occupied. This shifts the contributions of Co to lower energies. The corresponding shift, however, is larger for the onion-ring icosahedron, since the density of the L10 minority 3d states encounter a steep
