Field-induced metal-insulator transition in the<i>c</i>-axis resistivity of graphite
We show that the resistivities perpendicular ${\ensuremath{\rho}}_{c}$ and parallel ${\ensuremath{\rho}}_{a}$ to the basal planes of different graphite samples show similar magnetic-field-driven metal-insulator transitions at a field ${B}_{c}$\ensuremath{\sim}0.1 T applied parallel to the c axis. Our results demonstrate the universality of the recently found scaling in ${\ensuremath{\rho}}_{a}$ of graphite and indicate …
