Anisotropic charge dynamics in detwinned Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$

A. Dusza, A. Lucarelli, F. Pfuner +3

We investigate the optical conductivity as a function of temperature with light polarized along the in-plane orthorhombic $a$- and $b$-axes of Ba(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$ for $x…
