Magnetic and electronic properties of HOPG/MoF6 graphite intercalation compounds: An ESR study

Abstract
The diamagnetic MoF6 molecule intercalates into graphite (HOPG) according to the reaction nC+MoF6 → C+xn(MoF6)x (MoF6)1−x. Combination of ESR and magnetic susceptibility measurements indicate that the charge transfer is incomplete with x∼0.2. The system HOPG/MoF6 is unique in that ESR resonances due to both the 4d1 intercalant species (MoF6) and conduction carriers can be detected. The ESR spectra of stage III exhibit an additional resonance which is probably associated with graphite interior layers.
