Fe K-edge X-ray resonant magnetic scattering from Ba(Fe1-x Cox)2As2 superconductors

Journal Article · · European Physical Journal. Special Topics
We present an X-ray resonant magnetic scattering study at the Fe-K absorption edge of the BaFe2As2 compound. The energy spectrum of the resonant scattering, together with our calculation using the full-potential linear-augmented plane wave method with a local density functional suggests that the observed resonant scattering arises from electric dipole (E1) transitions. Finally, we discuss the role of Fe K-edge X-ray resonant magnetic scattering in understanding the relationship between the structure and the antiferromagnetic transition in the doped Ba(Fe1-x Co x )2As2 superconductors.
