Searching for a magnetic proximity effect in magnetite-carbon structures
R. Höhne, M. Ziese, P. Esquinazi
In order to study a possible magnetic proximity effect in magnetite-carbon structures, we have performed magnetization measurements of graphite-magnetite composites with different…
Magnetism in Carbon Structures
Pablo Esquinazi, Roland Höhne
We discuss different magnetic phenomena observed in carbon-based structures, in particular the diamagnetism, paramagnetism and ferromagnetism observed in graphite, disordered carbo…
Ferromagnetism in Oriented Graphite Samples
P. Esquinazi, A. Setzer, R. Hoehne +6
We have studied the magnetization of various, well characterized samples of highly oriented pyrolitic graphite (HOPG), Kish graphite and natural graphite to investigate the recentl…
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…
