Reentrant Metallic Behavior of Graphite in the Quantum Limit
arXiv:cond-mat/0209406 · doi:10.1103/PhysRevLett.90.156402
Abstract
Magnetotransport measurements performed on several well-characterized highly oriented pyrolitic graphite and single crystalline Kish graphite samples reveal a reentrant metallic behavior in the basal-plane resistance at high magnetic fields, when only the lowest Landau levels are occupied. The results suggest that the quantum Hall effect and Landau-level-quantization-induced superconducting correlations are relevant to understand the metallic-like state(s) in graphite in the quantum limit.
