In this work we have measured Co K- and L$$_{2,3}$$-edge X-ray absorption near edge structure (XANES) and Co L$$_{2,3}$$-edge X-ray magnetic circular dichroism (XMCD) spectra, and also carried out their calculations for C$$_{60}$$Co$$_x$$ compounds. The observed XANES and XMCD are sensitive to the Co concentration. In the low density region ($$x$$=1.0-1.5), one Co is surrounded by three C$$_{60}$$ balls. The Co L$$_{2,3}$$-edge XMCD analyses gives the spin magnetic moment on Co in the range 0.5-0.9 $$mu_B$$.
