The de Haas van Alphen (dHvA) effect of the stage-1 MoF6− graphite intercalation compound was investigated in magnetic fields up to 5.5 T. The dHvA-frequency spectrum of the stage-1 compound consists of a high frequency, a midfrequency, and a set of low frequencies. The dominant oscillation is the high frequency at 1530 T. It is associated with the single graphite energy band of the stage-1 compound. The cyclotron mass of the carrier with the dominant frequency is 0.31 m0 where m0 is the free-electron mass. The electron charge transfer per intercalated MoF6− molecule is 0.3 for the C8.4MoF6 compound. The low frequencies and midfrequencies are compared with those in other stage-1 chloride graphite intercalation compounds.

Stage 1

Intercalation of EuCl3 TbCl3, and AlCl3 into graphite was carried out in the presence of chlorine. The observation of products by x-ray diffraction showed that the extent of chloride intercalation could be controlled through adjustment of the pressure of chlorine; increasing pressure tended to increase the extent of intercalation. In the case of EuCl3, the extent of intercalation varied to show a stage transition. In contrast, TbCl3 intercalation gave a mixture of stage 2 or stage 4 graphite intercalation compound (GIC) and remaining graphite, where the extent of intercalation is revealed by the ratio of GIC to graphite. With respect to AlCl3 intercalation, although the preparation of stage 1, 2, and 4 GICs was successful, stage 3 and 5 GICs could not be obtained.
