Synchrotron Spectroscopic Experiments on Ruthenates

Abstract
Ruthenate-oxide materials attract much attention due to the interesting ground states they exhibit, such as unconventional superconductivity in Sr2RuO4 or Mott physics in Ca2RuO4. The role of electron correlations, Hund's coupling and spin-orbit interactions is still being debated and explored [1,2]. In this talk, we present recent experimental study on the Ru 4d-orbital occupation and excitations in (Ca/Sr)2RuO4, performed through a combination of synchrotron spectroscopic techniques.
