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 5d(3) system. The excitation is well
   described within a minimal model Hamiltonian with strong anisotropy and
   Heisenberg exchange (J(1) = J(2) = 13.9 meV). The observed behavior
   places NaOsO3 on the boundary between localized and itinerant magnetism.}},
