EPR and MMMA Study of C60upon K-Doping

EPR and ΜΜMΑ studies of C60 upon K-doping have been performed.Two different and welł separated EPR narrow lines were detected for C1-60 and C at temperatures below 100 K. Time dependent changes in the intensities of both CL and C3-60 lines were observed when the system undergoes an eutectoid transformation.The evolution of superconductivity with two T' related to dicherent valences (v) of C6Ó ion radicals have been found.
