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…
Co-substitution effects on the Fe-valence in the BaFe2As2 superconducting compound: A study of hard x-ray absorption spectroscopy
E. M. Bittar, C. Adriano, T. M. Garitezi +6
The Fe K X-ray absorption near edge structure (XANES) of BaFe2-xCoxAs2 superconductors was investigated. No appreciable alteration in shape or energy position of this edge was obse…
Pressure and chemical substitution effects in the local atomic structure of BaFe2As2
E. Granado, L. Mendonca-Ferreira, F. Garcia +10
The effects of K and Co substitutions and quasi-hydrostatic applied pressure (P<9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe{0.937}Co{0.063})2As2 and Ba{0.85}K{0.15}Fe2A…
