Comment on "Consistent Interpretation of the Low-Temperature Magnetotransport in Graphite Using the Slonczewski-Weiss-McClure 3D Band-Structure Calculations" (arXiv:0902.1925)

Abstract

In 2004 we have shown that substantial part of conductivity in graphite is provided by holes with massless linear spectrum - Dirac Fermions that coexist with massive normal carriers - electrons. In a recent Letter [Phys. Rev. Lett. 102, 166403 (2009), arXiv:0902.1925] Schneider et al. revised our conclusion pointed that both types of carriers are massive. Since both groups use the same method of phase determination of Shubnikov de Haas oscillation we comment here that the controversy originates from the improper treatment of experimental results in Schneider2009 et al
