The magnetic susceptibility of the first stage potassium graphite intercalation compound, of which the host graphite was grafoil sheets, was measured by the Hartshorn bridge method. The superconducting transition temperature of C 8.8 K was found to be 125 mK. The susceptibility fluctuation in the transition region was examined with Aslamazov-Larkin's theory, and the dimensionality in the transition region gradually changed as temperature was decreased toward T c .
