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