We study the anisotropic in-plane optical conductivity of detwinned Ba(Fe_(1-x)Co_x)_2As_2 single crystals for x=0, 2.5% and 4.5% in a broad energy range (3 meV-5 eV) across their structural and magnetic transitions. For temperatures...

I present our optical spectroscopic measurements on several different Fe-based superconducting systems. We find that, for all investigated FeAs-based compounds, the optical conductivity spectra contain, in addition to the free carrier response at low frequency, a peculiar temperature-dependent gap-like...
