Abstract
Subject headings
Close
- We present a comprehensive angle-resolved photoemission spectroscopy study of Ca1.8Sr0.2RuO4. Four distinct bands are revealed and along the Ru-O bond direction their orbital characters are identified through a light polarization analysis and comparison to dynamical mean-field theory calculations. Bands assigned to d(xz),d(yz) orbitals display Fermi liquid behavior with fourfold quasiparticle mass renormalization. Extremely heavy fermions-associated with a predominantly d(xy) band character-are shown to display non-Fermi-liquid behavior. We thus demonstrate that Ca1.8Sr0.2RuO4 is a hybrid metal with an orbitally selective Fermi liquid quasiparticle breakdown.
