Effects of Ru Substitution on Dimensionality and Electron Correlations in Ba(Fe_{1-x}Ru_x)_2As_2

N. Xu, T. Qian, P. Richard +12

We report a systematic angle-resolved photoemission spectroscopy study on Ba(Fe${}_{1-x}$Ru${}_x$)${}_2$As${}_2$ for a wide range of Ru concentrations (0.15 $\le$ \emph{x} $\le$ 0.74). W…
