Title: Strongly gapped spin-wave excitation in the insulating phase of NaOsO 3

Abstract

NaOsO3 hosts a rare manifestation of a metal-insulator transition driven by magnetic correlations, placing the magnetic exchange interactions in a central role. We use resonant inelastic x-ray scattering to directly probe these magnetic exchange interactions. A dispersive and strongly gapped (58 meV) excitation is observed indicating appreciable spin-orbit coupling in this 5d3 system. The excitation is well described within a minimal model Hamiltonian with strong anisotropy and Heisenberg exchange (J1 = J2 = 13.9 meV). As a result, the observed behavior places NaOsO3 on the boundary between localized and itinerant magnetism.

FIG. 1 FIG. 1: (a) Excitations measured in NaOsO3 at various fixed incident energies through the Os L-edge using RIXS. Three inelastic peaks are observed labeled EB, EC and ED. The solid (dashed) gray line indicates the incident energy that yields the maximum intensity for EB (EC). (b) RIXS measurement at fixedmore » incident energy of 10.88 keV. Main panel was measured with a resolution of ΔE=275 meV and the inset data was collected with ΔE=46 meV. The horizontal red lines indicate the FWHM experimental resolution. Measurements were performed at 300 K.« less
