Signatures of bi-altermagnetism revealed by sublattice-specific circular dichroism in resonant inelastic X-ray scattering
Researchers used sublattice-specific circular dichroism in resonant inelastic X-ray scattering (RIXS) to identify bi-altermagnetism in Fe2Mo3O8. They found two distinct magnetic sublattices, proving a new magnetic state exists. Theoretical modeling confirmed these findings by simulating the effects of altermagnetic order on electronic excitations.
