THE DE HAAS-VAN-ALPHEN EFFECT OF MOF6- INTERCALATED GRAPHITE

The de Haas van Alphen (dHvA) effect of the stage-1 MoF6- graphite int ercalation compound was investigated in magnetic fields up to 5.5 T. T he 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 ma ss of the carrier with the dominant frequency is 0.31m(0) where m(0) i s the free-electron mass. The electron charge transfer per intercalate d 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.
