Crystal structure and magnetic properties of EuxSr6-xC60 (x = 1, 3,6) were studied. They all have a bce structure which is an isostructure to other M6C60 (M is an alkali or alkaline earth metal). The lattice constants follow the Vegard's law, suggesting a formation of solid solution at x = 1 and 3. Magnetic measurements reveals all Eu atoms are in the divalent state with a magnetic moment of 7 mu (B) (S = 7/2), which is consistent with XANES experiments. Ferromagnetic correlation develops at low temperature in all three samples and seems to be caused the pi -f interaction through C-60 rather than the direct exchange interaction between Eu atoms.
