Abstract	Electrical conductivity and conduction ESR (CESR) for graphite intercalation compounds (GICs) with nitric acid C5nHNO3 (n 1⁄4 2, 3) have been measured. In the incommensurate phase of second stage compounds (210 K < T < 250 K) absence of temperature dependence of the c-axis conductivity, but preservation of the “metallic” temperature dependence of the basal plane conductivity, has been found. In the third stage compounds the similar “plateau” is a less marked one. In both stages of GICs investigated at the incommensurate crystallization of intercalate subsystem, the CESR linewidth undergoes a stepwise increase. It was shown that in GICs studied the c-axis conductivity is realized by means of a non-band mechanism, which might be the mechanism of transport of free charge carriers along the c-axis through the defect-mediated narrow high-conductivity paths (channels).
