High-field magnetotransmission investigation of natural graphite

Résumé

Magnetotransmission measurements in magnetic fields in the range B=20–60 T have been performed to probe the H- and K-point Landau level transitions in natural graphite. At the H point, two series of transitions, whose energy evolves as √B, are observed. A reduced Slonczewski-Weiss-McClure model with only two parameters to describe the intralayer (γ0) and interlayer (γ1) coupling correctly describes all observed transitions. Polarization-resolved measurements confirm that the observed apparent splitting of the H-point transitions at high magnetic field cannot be attributed to an asymmetry of the Dirac cone.
