“…The choice of the fundamental frequencies f 1 = 455 T and f 2 = 1106 T is in agreement with previous work on stage-2 SbCl 5 [14] intercalated graphite (where the two fundamental frequencies are f 1 = 422 T and f 2 = 1102 T) and on stage-2 InCl 3 GIC [12] for which f 1 = 467 T and f 2 = 1320 T.…”

“…The theoretical framework which incorporates experimental dHvA results and provides predictions for the Fermi level, charge transfer values and dispersion relations for acceptor GICs is provided by Blinowski et al [15]. The parameters in the model are the in-plane The model parameters are similar to those for other stage-2 acceptor GICs intercalated with BiCl 3 , SbCl 5 and BF − 4 [14,16] for which γ 0 = 2.40 eV and γ 1 = 0.38 eV from the Blinowski model. Thus the basic energy bands of all the stage-2 GICs are similar irrespective of whether there is zone folding.…”

The electronic properties of the stage-2 IBr graphite intercalation compound were investigated by means of the de Haas-van Alphen (dHvA) effect. Thirty dHvA frequencies were found with the magnetic field parallel to the c-axis. These results are explained by the Fermi surface model formed by zone folding resulting from commensurate ( √ 183R26.33 • × 2 √ 3R0 • ) in-plane superlattice translations which coupled carrier orbits. The unfolded Fermi surface was the primitive two-dimensional Fermi surface of Blinowski et al for graphite intercalation compounds. By adjusting the dimensions of this Fermi surface, all the dHvA frequencies were interpreted with an accuracy of ≈5%. The Fermi radii of the unfolded Fermi surface were k 1 = 0.118 Å−1 and k 2 = 0.183 Å−1 . The dHvA frequencies (455 and 1106 T) were used to determine the band parameters γ 0 (the interaction of nearest neighbours) and γ 1 (the interaction of nearest layers) in Blinowski's theoretical band model for acceptor-type graphite intercalation compounds.

“…Previous work on stage-2 SbCl 5 intercalated graphite 6 indicated that the two fundamental frequencies were in the ratio of 2.8:1 ͑1102 T:422 T͒. This is similar to those of other stage-2 compounds.…”

The de Haas-van Alphen ͑dHvA͒ effect of the stage-2 InCl 3 graphite intercalation compound was studied with two dHvA spectrometers, one providing fields up to 14 T and temperatures between 50 and 800 mK and the other up to 5.5 T in the temperature range 1.5-4.2 K. Fifteen dHvA frequencies were measured along with the cyclotron masses of many of them. The frequencies were explained by the zone folding of the two Fermi-surface cylinders of the stage-2 compound. The orbits were formed by translation of the 8ͱ3 ϫ8ͱ3R30°lattice of the intercalant molecules.
