Description
Synchrotron radiation photoemission studies show that the mixing of Mg, Sr, and Ba with C60 yields metallic (Sr and Ba) and nonmetallic (Mg) fullerides. In all cases, fulleride formation leads to the occupation of hybrid bands near the Fermi level that are derived from C60 states and the s states of the alkaline-earth atoms. The nonmetallic character of MgxC60 probably reflects electron correlation effects, and metallic SrxC60 and BaxC60 fullerides are candidates for superconductivity
