Noncollinear antiferromagnets can have additional spin Hall effects due to the net chirality of their magnetic spin structure, which provides for more complex spin-transport phenomena compared to ordinary nonmagnetic materials. Here we investigated how ferromagnetic resonance of permalloy (Ni80Fe20) is modulated by spin Hall effects in adjacent epitaxial IrMn3 films. We observe a large dc modulation of the ferromagnetic resonance linewidth for currents applied along the [001] IrMn3 direction. Furthermore, this very strong angular dependence of spin-orbit torques from dc currents through the bilayers can be explained by the magnetic spin Hall effect where IrMn3 provides novel pathways for modulating magnetization dynamics electrically.
