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…
Doping-induced superconductivity of ZrB and HfB
N. Barbero, T. Shiroka, B. Delley +5
Unlike the widely studied -type two-gap superconductor MgB, the chemically similar compounds ZrB and HfB do not superconduct above 1 K. Yet, it has been shown that s…
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…
Possible unconventional superconductivity in substituted BaFeAs revealed by magnetic pair-breaking studies
P. F. S. Rosa, C. Adriano, T. M. Garitezi +8
The possible existence of a sign-changing gap symmetry in BaFeAs-derived superconductors (SC) has been an exciting topic of research in the last few years. To further i…
Quantum Oscillations in EuFe2As2 single crystals
P. F. S. Rosa, B. Zeng, C. Adriano +6
Quantum oscillation measurements can provide important information about the Fermi surface (FS) properties of strongly correlated metals. Here, we report a Shubnikov-de Haas (SdH)…
Site specific spin dynamics in BaFe2As2: tuning the ground state by orbital differentiation
P. F. S. Rosa, C. Adriano, T. M. Garitezi +4
The role of orbital differentiation on the emergence of superconductivity in the Fe-based superconductors remains an open question to the scientific community. In this investigatio…
