Fig. 2: Electronic structure of Ca2RuO4 and Sr2RuO4 ground states.
From: Orbital-order as the driving mechanism for superconductivity in ruthenates
Density of states (in states/eV/f.u) for spin up (positive values) and spin down (negative values) channels as a function of the energy (in eV) projected on Ru d (black line) and O p (blue filled area) states for Ca2RuO4 (a) and Sr2RuO4 (b) ground states. Projection on dxy (red line), dxz and dyz (grey line), and dx2-y2 and dz2 (orange line) orbitals around the valence and maximum is provided as inserts. The AFM-C and FM orders are used for Ca2RuO4 and Sr2RuO4, respectively. The black dashed vertical line represents the valence band maximum or the Fermi level.
