    • Co-cubstitution effects on the Fe valence in the BaFe2As2 superconducting compound : a study of hard x-ray absorption spectroscopy 

      Bittar, Eduardo Matzenbacher; Adriano, C.; Garitezi, T. M.; Rosa, P. F. S.; Ferreira, Leticie Mendonca; Garcia, Flávio; Azevedo, Gustavo de Medeiros; Pagliuso, P. G. (2011) [Artigo de periódico]
      The Fe K x-ray absorption near edge structure of BaFe₂-xCoxAs₂ superconductors was investigated. No appreciable alteration in shape or energy position of this edge was observed with Co substitution. This result provides ...

    • Magnetotransport properties in the magnetic phase of BaFe2−xTxAs2 (T = Co,Ni) : a magnetic excitations approach 

      Peña Pacheco, Jully Paola; Piva, M. M.; Rosa, P. F. S.; Pagliuso, P. G.; Adriano, C.; Grant, Ted W.; Fisk, Zachary; Baggio-Saitovitch, E.; Pureur Neto, Paulo (2018) [Artigo de periódico]
      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. Here, we report on the electrical resistivity, ...

    • Pressure and chemical substitution effects in the local atomic structure of BaFe2As2 

      Granado, E.; Ferreira, Leticie Mendonca; Garcia, Flávio; Azevedo, Gustavo de Medeiros; Fabbris, Gilberto Fernandes Lopes; Bittar, Eduardo Matzenbacher; Adriano, C.; Garitezi, T. M.; Rosa, P. F. S.; Bufaiçal, L. F.; Avila, M. A.; Terashita, H.; Pagliuso, P. G. (2011) [Artigo de periódico]
      The effects of K and Co substitutions and quasihydrostatic applied pressure (P < 9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe0.937Co0.063)2As2 and Ba0.85K0.15Fe2As2 superconductors were investigated by extended ...
