EPR studies of superconducting fullerites Me x C 60 (Me = K and Rb) are performed for temperatures ranging from 4 to 300 K and compositions of x = 2 to 5. A paramagnetic center is an ion radical fullerene Ċ 60 which may occur as a cation Ċ 60 + or anion Ċ 60 y − of different valency. The EPR signal of Ċ 60 + weakly depends on temperature whereas the signal of Ċ 60 y − in a Me x (Ċ 60 ) y − complex is strongly dependent both on temperature and composition. A model of a paramagnetic center related to a wandering electron (hole) localized on the Ċ 60 fullerene ball is presented.
