Altermagnetism produces pair emission and absorption from dark excitons and magnons in LaOMnSe
Birender Singh, Xian Xu, Sabrina R. Hatt +21
Altermagnets' (AMs) non-relativistic spin splitting enables novel states, spintronic and magneto-optical devices, though their optical signatures remain elusive. Here, we report ex…

LaOMnSe: a correlated insulating layered d-wave altermagnet
Chao-Chun Wei, Xiaoyin Li, Sabrina Hatt +12
Altermagnets represent a new class of magnetic phases without net magnetization that are invariant under a combination of rotation and time reversal. Unlike conventional collinear…
