Ls. Sochava et al., EPR STUDY OF THE HOLE PARAMAGNETIC CENTER IN C-70 FULLERITE, Radiation effects and defects in solids, 137(1-4), 1995, pp. 1341-1343
The hole paramagnetic center (S = 1/2, g = 2.0028) was observed in und
oped C-70 fullerite for the first time. It was shown that the possible
model of this center is C-60(+)-hole center with charge compensation
at the surface.
