In most collinear antiferromagnets, PT symmetry leads to a lack of spin-polarization. Here, Gurung et al show that a noncollinear antiferromagnets can exhibit an extremely high degree of spin polarization over a large area of its Fermi surface and propose using this feature for the development of antiferromagnetic magnetic tunnel junctions.
