✦ Synopsis

The temperature zerland). '33Cs and 'Li NMR measurements on intervariation of the in-plane thermal conductivities in the calated C&s and C,Li samples of HOPG and C&s range 2 < T < 300K are reported for stages 2, 3 and 6 powder samples are reported. The isotropic and axial FeC& and a stage-5 potassium graphite intercalation part of the Knight shift K and the electric field gradient compounds. Thermopower data are also presented for have been determined. K is considerably lowered comthe FeCls compounds.

pared to Cs and Li metal, respectively. For C&s this is mainly due to a reduction of N(&) whereas for C6Li 47. Pressure-dependent resfstivfty of graphite intercalation charge transfer is also important.
