Phase analysis of quantum oscillations in graphite
Igor A. Luk'yanchuk, Yakov Kopelevich
The quantum de Haas van Alphen (dHvA) and Shubnikov de Haas (SdH) oscillations measured in graphite were decomposed by pass-band filtering onto contributions from three different g…
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…
Field distribution and flux-line depinning in the mixed-state of MgB2 probed by Conduction Electron Spin Resonance
R. R. Urbano, P. G. Pagliuso, C. Rettori +3
We report the first observation of the internal magnetic-field distribution and flux-line depinning in the vortex-state of a type-II superconductor probed by conduction electrons s…
Current-Induced Superconductor-Insulator Transition in Granular High-T_c Superconductors
Y. Kopelevich, C. A. M. dos Santos, S. Moehlecke +1
In this work we report a systematic study of electrical current effects on superconducting properties of granular YPrBaCuO samples with x close to…
Comment on ``New Vortex-Matter Size Effect Observed in BiSrCaCuO"
Y. Kopelevich, P. Esquinazi
The Letter of Wang et al. \cite{wan} is related to the recently discovered vanishing of the second magnetization peak (SMP) in high- superconductors reducing the sample size \…
Comment on "Quantum Melting of the Quasi-Two-Dimensional Vortex Lattice in "
Y. Kopelevich, P. Esquinazi
In a recent Letter Mola et al. \cite{mola} reported magnetization measurements performed on the organic superconductor (ET)Cu(NCS) K) as a function…
