Summary

Story summary

Researchers used Resonant Inelastic X-ray Scattering (RIXS) to study the altermagnetic properties of chromium antimonide (CrSb) and observed a dichroic asymmetry in magnon peak intensity.
The dichroism reverses when the Néel vector is inverted, indicating distinct antiferromagnetic domains.
The experimental results align with theoretical predictions, showing good agreement in magnon band structures.
The findings demonstrate RIXS's potential to explore altermagnetic magnons in CrSb and advance understanding of its magnetic behavior.
