Spin-Polarized Current in Noncollinear Antiferromagnets
Spin-Polarized Current in Noncollinear Antiferromagnets
Noncollinear antiferromagnets, such as Mn_{3}Sn and Mn_{3}Ir, were recently shown to be analogous to ferromagnets in that they have a large anomalous Hall effect. Here we show that these materials are similar to ferromagnets in another aspect: the charge current in these materials is spin polarized. In addition, we show …
