Description
We investigated persistent spin polarization in the altermagnet V2Te2O under the addition of spin-orbit coupling. We proposed the realization of collinear persistent altermagnetic spin polarization protected by mirror symmetry in a subclass of 2D altermagnets in the presence of spin-orbit, referred to as persistent altermagnetism. We showed that mirror symmetry protected persistent altermangetism can also emerge in 2D Brillouin Zone sections of 3D altermagnets. Persistent altermagnets are advantageous due to their large nonrelativistic collinear spin splitting, offering promising material realizations for spintronic applications with long spin lifetimes and efficient spin accumulation.
