Fig. 5: Effective spin polarization of different noncollinear antiferromagnets.

Calculated components of spin polarization \({{\boldsymbol{p}}}_{{{\boldsymbol{k}}}_{{\|}}}=({p}_{{{\boldsymbol{k}}}_{{\|}}}^{x},{p}_{{{\boldsymbol{k}}}_{{\|}}}^{y},{p}_{{{\boldsymbol{k}}}_{{\|}}}^{z})\) (a) and spin polarization magnitudes \({p}_{{{\boldsymbol{k}}}_{{\|}}}\equiv {{|}}{{\boldsymbol{p}}}_{{{\boldsymbol{k}}}_{{\|}}}{{|}}\) (b) for Mn₃GaN in the \({\Gamma }_{4g}\) phase, Mn₃Ir \(({\Gamma }_{4g})\), Mn₃Pt \(({\Gamma }_{4g})\), Mn₃NiN \(({\Gamma }_{4g})\), Mn₃SnN \(({\Gamma }_{5g})\), and Mn₃Sn.
