Abstract.
We propose a theoretical model to account for the recently observed magnetic moment reduction of gadolinium in fullerenes. While this reduction has been observed also for other trivalent rare-earth atoms (Dy3+, Er3+, Ho3+) in fullerenes, and can be ascribed to crystal field effects, the explanation of this phenomena for Gd3+ is not straightforward due to the spherical nature of its ground state (S=7/2, L=0). In our model the momentum reduction is the result of a subtle interplay between hybridisation and the spin-orbit interaction.
