Impact of the Spin Density Wave Order on the Superconducting Gap of Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$

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

We report a doping dependent electronic Raman scattering measurements on iron-pnictide superconductor Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ single crystals. A strongly anisotropic gap is…
