Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic $\alpha$-MnTe

Mathews Benny, Xujia Gong, Amar Fakhredine +21

Altermagnetic $\alpha$-MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clar…
