【 摘 要 】

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 root B, are observed. A reduced Slonczewski-Weiss-McClure model with only two parameters to describe the intralayer (gamma(0)) and interlayer (gamma(1)) 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.
