Abstract
The results of an in situ conduction electron spin resonance (CESR) study of the intercalation of SbF5 molecules into highly oriented pyrolytic graphite are presented. The narrowing (broad-ening) of the CESR signal from intercalated (nonintercalated) parts of the graphite plate during advance of the reaction front into graphite is explained by the nonzero probability of the spin reorientation at collisions of current carriers with the intercalation front and by a decrease (increase) of frequency of these collisions. The assumption was made that the stepwise increase in the intensity of the CESR signal from intercalated parts of the graphite plate during the reaction is due to the presence of an intercalation threshold and periodical impoverishing of the adsorbed layers of the intercalant. The results of calculations conducted within the framework of this model fit the experimental data well.
