Abstract

Time resolved ESR studies of some acceptor type GIC, HOPG/AsF₅ and HOPG/BF₃/F₂, are reported. Free induction decay (FID) spectroscopy yields the dynamical relaxation time T₂^* associated with mobile spins. T₂^* was found to be almost isotropic and only slightly temperature dependent. T₂^* times are consistent with CW-ESR linewidths measured on the same samples. In additionn, we found a weak Hahn echo at g ≈ 2 for several HOPG/AsF₅ GIC below T = 20K. The Hahn echo signal is attributed to localized spins on the graphite layers.
