Spectroscopic analysis reveals distinct bond-directional magnetic excitations in the Kitaev material Na2IrO3, highlighting dominant Kitaev interactions that persist in the ordered state.

Key Points

To directly detect and characterize elusive bond-directional magnetic excitations resulting from anisotropic spin-spin interactions in the candidate Kitaev magnet Na2IrO3.
Utilized resonant inelastic X-ray scattering (RIXS) with a scattering plane defined by a specific bond and its associated spin component.
Scanned momentum transfer across a reciprocal space range spanning multiple Brillouin zones.
Identified distinct bond-directional characters of magnetic excitations at ~10 meV and ~45 meV.
Demonstrated that bond-directional nearest-neighbor excitations serve as a signature of dominant Kitaev interactions and persist within the magnetically ordered state.
