Abstract

Order-disorder phase transitions in AsF₅/GICs (HOPG, Fibers) can be probed by the hysteresis in the temperature dependence of the CESR linewidth. Evidence for in-plane phase transitions at ∼240K and ∼200K were observed for AsF₅/HOPG stage I in rough agreement with X-ray and neutron scattering studies. The high temperature phase transition was also observed in fibers. Quenching to temperatures below the melting point yields time dependent CESR linewidths. This time dependence is associated with domain growth. No time dependence CESR could be observed in stage II AsF₅/HOPG or in intercalated fibers.
