Altermagnetism produces pair emission and absorption from dark excitons and magnons in La $_{2}$ O $_{3}$ Mn $_{2}$ Se $_{2}$

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…

Cluster spin glass correlations and dynamics in Zn $_{0.5}$ Mn $_{0.5}$ Te

Sabrina R. Hatt, Camille Shaw, Emma Zappala +6

We present a magnetometry, muon spin relaxation ( $μ$ SR), and neutron scattering study of the insulating face-centered-cubic spin glass Zn $_{0.5}$ Mn $_{0.5}$ Te. The magnetometry and…

La $_{2}$ O $_{3}$ Mn $_{2}$ Se $_{2}$ : 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…
