Analogue of the quantum Hall effect for neutral particles with magnetic dipole moment
L. R. Ribeiro, E. Passos, C. Furtado +1
In this paper we investigate a possibility for the existence of an analog of the Quantum Hall Effect for neutral particles with a permanent magnetic moment in the presence of c…
Analog of Fishtail Anomaly in Plastically Deformed Graphene
S. Sergeenkov, F. M. Araujo-Moreira
By introducing a strain rate generated pseudo-electric field, we discuss a magnetic response of a plastically deformed graphene. Our results demonstrate the appearance of dislocati…
Pinning of spiral fluxons by giant screw dislocations in YBa_2Cu_3O_7 single crystals: Josephson analog of the fishtail effect
S. Sergeenkov, L. Jr. Cichetto, V. A. G. Rivera +4
By using a highly sensitive homemade AC magnetic susceptibility technique, the magnetic flux penetration has been measured in YBa_2Cu_3O_7 single crystals with giant screw dislocat…
Manifestation of geometric resonance in current dependence of AC susceptibility for unshunted array of Nb-AlOx-Nb Josephson junctions
V. A. G. Rivera, S. Sergeenkov, E. Marega +1
A pronounced resonance-like structure has been observed in the current dependence of AC susceptibility for two-dimensional array of unshunted Nb-AlOx-Nb Josephson junctions. Using…
Temperature oscillations of magnetization observed in nanofluid ferromagnetic graphite
S. Sergeenkov, N. S. Souza, C. Speglich +5
We report on unusual magnetic properties observed in the nanofluid room-temperature ferromagnetic graphite (with an average particle size of l=10nm). More precisely, the measured m…
Synthesis, characterization and magnetic properties of room-temperature nanofluid ferromagnetic graphite
N. S. Souza, S. Sergeenkov, C. Speglich +7
We report the chemical synthesis route, structural characterization, and physical properties of nanofluid magnetic graphite (NFMG) obtained from the previously synthesized bulk org…
