Ni/Bi bilayers: The effect of thickness on the superconducting properties
Gabriel Sant'ana, David Möckli, Alexandre da Cas Viegas +2
Nickel/Bismuth (Ni/Bi) bilayers have recently attracted attention due to the occurrence of time-reversal symmetry breaking in the superconducting state. Here, we report on the stru…
Spin-Orbit Proximity Effect in Bi/Co Multilayer: The Role of Interface Scattering
Arthur Casa Nova Nonnig, Alexandre da Cas Viegas, Fabiano Mesquita da Rosa +2
The Spin-Orbit Proximity Effect is the raise of Spin-Orbit Coupling at a layer near to the interface with a strong spin-orbit material. It has been seen in several system such as g…
Effects of the pseudo-gap on the field-induced kinetic energy density of BiSrCaCuO single crystals
Lutiene F. Lopes, Jully P. Peña, Milton A. Tumelero +3
We report on magnetization experiments from which we obtain the field-induced kinetic energy density, , in the superconducting phase of several BiSrCaCuO s…
Magnetotransport properties in the magnetic phase of BaFeTAs (T = Co,Ni): A magnetic excitations approach
J. P. Peña, M. M. Piva, P. F. S. Rosa +6
Because of their complex Fermi surfaces, the identification of the physical phenomena contributing to electronic scattering in the Fe-based superconductors is a difficult task. Her…
The role of magnetic excitations in magnetoresistance and Hall effect of slightly TM-substituted BaFeAs compounds (TM = Mn, Cu, Ni)
J. P. Peña, M. M. Piva, C. B. R. Jesus +10
We report on electrical resistivity, magnetoresistance (MR) and Hall effect measurements in four non-superconducting BaFeTMAs (TM = Mn, Cu and Ni) single crystals w…
Spin texture on top of vortex avalanches in Nb/Al_2O_3/Co thin film heterostructures
R. F. Lopes, D. Carmo, F. Colauto +5
We report on magneto-optical imaging, magnetization, Hall effect and magneto-resistance experiments in Nb/Al_2O_3/Co thin film heterostructures. The magnetic field is applied perpe…
Magnetic, electrical and structural properties of the new Re-doped ruthenocuprate Ru1-xRexSr2GdCu2Oy
L. T. Corredor, J. Albino Aguiar, D. A. Landínez Téllez +3
Despite the discovery of new superconductors classes, high-Tc oxides continue to be a current topic, because of their complex phase diagrams and doping-dependant effects (allowing…
Magnetic measurements and kinetic energy of the superconducting condensate in SmBa_2Cu_3O_{7-δ}
J. P. Peña, D. Martínez B., C. A. Parra Vargas +3
We report in-field kinetic energy results in the temperature region closely below the transition temperature of two differently prepared polycrystalline samples of the superconduct…
