“…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 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.

“…The zone-folding effect has been detected experimentally in stage-1 InCl 3 GIC [11], stage-2 InCl 3 GIC [12] and stage-2 SbCl 5 GIC [13]. For the stage-2 InCl 3 GIC [12] the dHvA frequencies were in the range 126-1424 T and the cyclotron masses were between 0.095 and 0.27 m 0 . There were at least 15 dHvA frequencies observed.…”
