What controls the phase diagram and superconductivity in Ru substituted BaFe${}_2$As${}_2$?

R. S. Dhaka, Chang Liu, R. M. Fernandes +8

We use high resolution angle-resolved photoemission to study the electronic structure of the iron based high-temperature superconductors Ba(Fe${}_{1-x}$Ru${}_x$)${}_2$As${}_2$ as a functio…
