Abstract
The in-plane resistivity {A figure is presented}a, and the c-axis resistivity, {A figure is presented}-1c, of HOPG/IrF6 were measured as a function of temperature and intercalant concentration. {A figure is presented}a could be fitted to the equation {A figure is presented}a = A+BT+CT2 but exhibits a shallow minimum for some of the stage I GIC. {A figure is presented}c is metallic and d{A figure is presented}c/dT exhibits nonmonotonic behaviour suggesting a first order phase transition at Tc = 240K for C10IrF6 (st. I). Neutron scattering measurements suggest a liquid to incommensurate three dimensional solid phase transition.
