Abstract

We report a systematic angle-resolved photoemission spectroscopy study on Ba(Fe _1-xRu _x) ₂As ₂ for a wide range of Ru concentrations (0.15≤x≤0.74). We observed a crossover from two dimensions to three dimensions for some of the holelike Fermi surfaces with Ru substitution and a large reduction in the mass renormalization close to optimal doping. These results suggest that isovalent Ru substitution has remarkable effects on the low-energy electron excitations, which are important for the evolution of superconductivity and antiferromagnetism in this system.
