The low-frequency de Haas-van Alphen (dHvA) oscillation of the stage-1 CdCl2 graphite intercalation compound (GIC) and of the SbF6- compound was investigated as a function of magnetic-field direction θ with respect to the c axis. For the angular range of measurement of 0<θ<20° the frequency was independent of θ within experimental uncertainty in both compounds and did not follow the relation fθ=f0secθ for a cylindrical Fermi surface. For the angular range of measurement, the extremal cross-sectional areas of the Fermi surface for the low-frequency are that of a sphere. This indicates a significant three-dimensional component of the graphitic energy band for the low frequency.
