EPR and ΜΜMΑ studies of C_{60} upon K-doping have been performed. Two different and well separated EPR narrow lines were detected for C^{1-}_{60} and C at temperatures below 100 K. Time dependent changes in the intensities of both and C^{3-}_{60} lines were observed when the system undergoes an eutectoid transformation. The evolution of superconductivity with two T_{c} related to different valences (v) of C^{v}_{60} ion radicals have been found.
