Abstract :

The thermal conductivity and thermoelectric power (TEP) of a stage-3 graphite-CoCl/sub 2/ intercalation compound have been measured between 4 and 300K. In the temperature region 4</b T/<13K there appears a contribution to the thermal conductivity in addition to the one that is linear in /b T/ and associated with free carriers. This additional contribution reaches a maximum near 9.5K. At that temperature the curve of TEP vs. /b T/ displays a sharp break in slope. The temperature of these anomalies is consistent with the temperature of a magnetic phase transition deduced from magnetic susceptibility and heat capacity measurements.
