摘要：
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 gamma Fermi surface sheet derived from the in-plane Ru 4d(xy) orbital. The kink of gamma Fermi surface sheet was still observed at points far from (0, pi), indicating a rather weak momentum dependence of the kink of Sr2RuO4. (c) 2006 Elsevier B.V. All rights reserved.
