Anomalous Hall Effect in Graphite
Y. Kopelevich, J. C. Medina Pantoja, R. R. da Silva +2
We report on the experimental observation of an anomalous Hall effect (AHE) in highly oriented pyrolytic graphite samples. The overall data indicate that the AHE in graphite can be…
Metal-Insulator-Metal Transitions, Superconductivity and Magnetism in Graphite
Y. Kopelevich, P. Esquinazi, J. H. S. Torres +4
This article reviews recent results of magnetotransport and magnetization measurements performed on highly oriented pyrolitic graphite (HOPG) and single crystalline Kish graphite s…
Reentrant Metallic Behavior of Graphite in the Quantum Limit
Y. Kopelevich, J. H. S. Torres, R. R. da Silva +3
Magnetotransport measurements performed on several well-characterized highly oriented pyrolitic graphite and single crystalline Kish graphite samples reveal a reentrant metallic be…
Magnetic-Field-Driven Superconductor-Insulator-Type Transition in Graphite
H. Kempa, Y. Kopelevich, F. Mrowka +4
A magnetic-field-driven transition from metallic- to semiconducting-type behavior in the basal-plane resistance takes place in highly oriented pyrolytic graphite at a field $H_c \s…
Nonlinear ac susceptibility studies of high- rings: Influence of the structuring method and determination of the flux creep exponent
S. Streubel, F. Mrowka, M. Wurlitzer +2
We have studied the influence of the patterning procedure on the critical current density of high- YBaCuO thin rings using the nonlinear ac susceptibility meth…
