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) [Artículo 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 ...
