抄録

Resistivity (ρ), Hall coefficient (R_H) and transverse magnetoresistance (tMR) of C₈K(1st) and C_12NK(N-th stage, N=2, 3 and 4) at temperatures of 1.2 to 300 K have been investigated in connection with the study of the Fermi surfaces (Part I). Resistivities in the N≥2 stage compounds show some anomalies which are associated with the order-disorder phase transitions. In C₈K, ρ has a temperature dependence of a+bT+cT². The temperature dependence of R_H indicates the one-electron conduction for the N≥2 compounds and the two-carriers one for C₈K. The tMR of each compound is represented by a linear function of magnetic field at about 4 to 15 T. The angular dependence of tMR indicates the cylindrical Fermi surface in a whole. The charge transfer rate from potassium to the graphite band is evaluated as 0.1 to 0.4 electron per atom for the 1st to 4th stage compounds.
