Reentrant Metallic Behavior of Graphite in the Quantum Limit
Reentrant Metallic Behavior of Graphite in the Quantum Limit
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 …
