Raman scattering study of Spin-Density-Wave order and electron-phonon coupling in Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$

L. Chauvière, Y. Gallais, M. Cazayous +4

We report Raman scattering measurements on iron-pnictide superconductor Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ single crystals with varying cobalt $x$ content. The electronic Raman continu…
