Phonon anomalies have been reported in iron-pnictide superconductors indicating a diverse interplay between different orders in the materials. Here, we report Raman scattering measurements on Sr(Fe_(...
We measured the infrared reflectivity of BaFe1.904Ni0.096As2 single crystal from room temperature down to 20 K.Two Drude terms and a Lorentz term well describe the real part of the optical conductivi...
We report electronic Raman scattering measurements on Ba(Fei_(1-x)Co_x)_2As_2(x = 0.065 and 0.2) single crystals with Raman shifts from 9 cm~(-1) up to 600 cm~(-1) in the symmetry of B_(lg) with resp...
