Abstract :
We investigated the interlayer coherency and angular-dependent magnetoresistance oscillations (AMROs) in magnetic graphite intercalation compounds (GICs), stage-1 FeCl3 GIC (S = 5/2) and stage-5 MoCl5 GIC (S = 1/2), where sufficiently strong π-d coupling is expected. Shubnikov-de Haas (SdH) oscillations were observable in a limited field-angle region. Standard AMRO was observed for both GICs, but the background of the angular-dependent magnetoresistance cannot be interpreted by the semi-classical model, based on the Boltzmann coherent transport theory. The resistance peak in magnetic fields parallel to the conduction layers is observed only for stage-5 MoCl5 GIC, demonstrating coherent transport. The results are discussed in terms of magnetic scattering in the characteristic stacking structure of GICs.
