| Abstract: | The de Haas-van Alphen (dHvA) effect of SbCl5-graphite intercalation compounds of stage 2, 3 and 4, and residual HNO3-compound of stage 3 has been studied. The dHvA spectra are stage dependent, and no combination frequency relations are found, which are in disagreement with Batallan et al.'s report. The amount of charge transfer per intercalant estimated on the basis of the rigid band model is 0.44, 0.49 and 0.43 for stage 4, 3 and 2 SbCl5-compounds and is 0.14 for stage 3 HNO3-compound. |
