The de Haas-van Alphen (DHVA) effect of the stage-1 AlCl 3 graphite intercalation compound has been studied in the temperature range from 1.5 K to 4.2 K with magnetic fields of 2.5 to 5 T. There is a dominant oscillation with a frequency of 1250 T with the magnetic field parallel to the c axis, which corresponds to an extremal cross sectional Fermi surface area of 0.119 AA -2 . The charge transfer per C atom is 0.032e + . The cyclotron mass is (0.261+or-0.001) m 0 . The Fermi energy determined from the Holzwarth band model is -1.14 eV. No bearing of the dominant frequency is observed in the 2.5 to 5 T field range, which indicates little undulation of the Fermi surface along the c axis. The Dingle temperature T D of one sample is (3.1+or-0.2) K, which corresponds to a mean free path l D of (4.8+or-0.4)*10 3 AA.
