The de Haas van Alphen effect of MoF6− intercalated graphite

Abstract

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.
