Abstract
The study of the origin of paramagnetism in fluorinated graphics by means o f EPR and F-19 NMR spin-lattice relaxation measurements is presented. We sh ow that paramagnetism in fluorinated graphite is caused by local magnetic m oments of dangling bonds. Localized spins in the high fluorine concentratio n region behave like isolated spins. In the partially fluorinated samples, strong exchange interaction between localized moments is observed. (C) 2001 Elsevier Science Ltd. All rights reserved.
