Abstract

We show that the resistivity perpendicular and parallel to the basal planes of different graphite samples show similar magnetic-field-driven metal-insulator-transitions at a field applied parallel to the c-axis. Our results demonstrate the universality of the recently found scaling in of graphite and indicate that the metallic-like temperature dependence of is directly correlated to that of . The similar magnetoresistance found for both resistivities, the violation of Kohler's rule and the field-induced transition indicate that the semiclassical transport theory is inadecuate to understand the transport properties of graphite.
