Abstract
We have performed a high-resolution angle-resolved photoemission spectroscopy on the monolayer strontium ruthenate Sr2RuO4, to elucidate the origin of the kink. We present the Fermi surface mapping and the detailed energy dispersions near the Fermi level. The kink was clearly observed for γ Fermi surface sheet derived from the in-plane Ru 4dxy orbital. The kink of γ Fermi surface sheet was still observed at points far from (0, π), indicating a rather weak momentum dependence of the kink of Sr2RuO4.
