EPR and MMMA studies of C-60 upon It-doping have been performed. Two d
ifferent and well separated EPR narrow lines were detected for C-60(1-
) and C-60(3-) at temperatures below 100 It. Time dependent changes in
the intensities of both C-60(1-) and C-60(3-) Lines were observed whe
n the system undergoes an eutectoid transformation. The evolution of s
uperconductivity with two T-c related to different valences (upsilon)
of C-60(upsilon-)-ion radicals have been found.
