Query: Field-induced metal-insulator Field-induced metal-insulator transition
  in the c-axis resistivity of graphite   We show that the resistivity perpendicular $\rho_c$ and parallel $\rho_a$ to
the basal planes of different graphite samples show similar
magnetic-field-driven metal-insulator-transitions at a field $B_c \sim 0.1 T$
applied parallel to the c-axis. Our results demonstrate the universality of the
recently found scaling in $\rho_a$ of graphite and indicate that the
metallic-like temperature dependence of $\rho_c$ is directly correlated to that
of $\rho_a$. 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.
