What is Orbital ordering and magnetism in layered Perovskite Ruthenate Sr~2~RuO~4~ about?
## Abstract Local density approximation plus on-site Coulomb interaction U electronic structure calculations reveal that layered perovskite oxide Sr~2~RuO~4~ exhibits the ferromagnetic (FM) half-metallic ground state, which is nearly degenerate with the antiferromagnetic (AFM) phase with a slightly higher total energy. The nearly degenerate FM/AFM total energies provide a reasonable explanation for the experimentally observed spin-fluctuation. In addition, a dumbbell-shape 4d − t~2g~ recombined d~xz~ − d~yz~ orbital ordering on the Ru sublattice is obtained owing to the on-site Coulomb interaction U associated with the elongated RuO~6~ octahedron local structure. The discovered orbital ordering is robust against the spin-orbit interaction as well as the surface terminations. Our findings unravel the on-site Coulomb correlation as the driving force of the Ru-4d orbital ordering as well as the inherent magnetic degeneracy.
