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…
Structural properties and Raman spectra of columbite-type NiNbVO synthesized under high pressure
Jully P. Peña, Pierre Bouvier, Oliver Isnard
The complete set of structural parameters of the new series of compounds NiNbVO () with the unusual columbite-type structure is presented here. In t…
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…
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…
