New Fermi Surface Sheets Revealed in Sr2RuO4 Revealed by High Resolution Angle-Resolved Photoemission Spectroscopy

ORAL

Abstract

We will present our detailed Fermi surface measurements on Sr2RuO4 by high resolution angle-resolved photoemission spectroscopy (ARPES) including vacuum ultra-violet (VUV) laser-based ARPES. In addition to the three sets of Fermi surface sheets originating from the bulk bands, the surface bands and the shadow bands of the surface bands, we have revealed two new Fermi surface sheets. The origin of these new Fermi surface sheets will be discussed.
