Oxygen adsorption effect on magnetic properties of graphite
D. W. Boukhvalov, S. Moehlecke, R. R. da Silva +1
Both experimental and theoretical studies of the magnetic properties of micrographite and nanographite indicate a crucial role of the partial oxidation of graphitic zigzag edges in…
Ferromagnetic and superconducting instabilities in graphite
Y. Kopelevich, S. Moehlecke, R. R. da Silva
We review our recent work on magnetic properties of graphite and related carbon materials. The results demonstrate that a structural disorder, topological defects, as well as adsor…
Universal Magnetic-Field-Driven Metal-Insulator-Metal Transformations in Graphite and Bismuth
Y. Kopelevich, J. C. Medina Pantoja, R. R. da Silva +1
Applied magnetic field induces metal - insulator and re-entrant insulator-metal transitions in both graphite and rhombohedral bismuth. The corresponding transition boundaries plott…
Interaction Between Superconducting and Ferromagnetic Order Parameters in Graphite-Sulfur Composites
S. Moehlecke, Y. Kopelevich, M. B. Maple
The superconductivity of graphite-sulfur composites is highly anisotropic and associated with the graphite planes. The superconducting state coexists with the ferromagnetism of pur…
Vortex Lattice in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} Well Above the First-Order Phase-Transition Boundary
J. H. S. Torres, R. Ricardo da Silva, S. Moehlecke +1
Measurements of non-local in-plane resistance originating from transverse vortex-vortex correlations have been performed on a Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} high-T_c superconductor in…
Magnetic Relaxation in the Peak Effect Region of CeRu
P. -C. Ho, S. Moehlecke, M. B. Maple
The different pinning strengths of the flux line lattice in the peak effect (PE) region of a polycrystalline sample of CeRu with a superconducting transition temperature {$T_c…
