Angle-resolved photoemission spectroscopy study of Ba(Fe$_{1-x}$Ru$_{x})_{2}$As$_{2}$
ORAL
Abstract
Ru-doped BaFe$_{2}$As$_{2}$ compounds were discovered to show superconductivity in a relatively wide doping range. We have performed angle-resolved photoemission spectroscopy measurements on a series of Ru-doped BaFe$_{2}$As$_{2}$ samples. We observed that band dispersions become more three-dimensional and Fermi velocities increase significantly with Ru doping. We will report these results and discuss implications to its superconductivity.
