Abstract:We investigate the electronic structure of two Ir 5+ honeycomb iridates, Sr3CaIr2O9 and NaIrO3, by means of resonant x-ray techniques. We confirm that Sr3CaIr2O9 realizes a large spin-orbit driven non-magnetic J = 0 singlet ground state despite sizable tetragonal distortions of Ir coordinating octahedra. On the other hand, the resonant inelastic x-ray spectra of NaIrO3 are drastically different from expectations for a Mott insulator with octahedrally coordinated Ir 5+ . We find that the data for NaIrO3 can be … Show more
