Suppression of backward scattering of Dirac fermions in iron pnictides Ba(Fe${}_{1-x}$Ru${}_x$As)${}_2$

Y. Tanabe, K. K. Huynh, T. Urata +5

We report electronic transport of Dirac cones when Fe is replaced by Ru, which has an isoelectronic electron configuration to Fe, using single crystals of Ba(Fe${}_{1-x}$Ru${}_x$As)$_2…
