| 中文摘要 | We report a systematic angle-resolved photoemission spectroscopy study on Ba(Fe1-xRux)(2)As-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. |
