The study of the origin of paramagnetism in fluorinated graphics by means of EPR and 19F NMR spin–lattice relaxation measurements is presented. We show that paramagnetism in fluorinated graphite is caused by local magnetic moments of dangling bonds. Localized spins in the high fluorine concentration region behave like isolated spins. In the partially fluorinated samples, strong exchange interaction between localized moments is observed.
