Observing oscillations using the non-magnetic and magnetic spin Hall effect in a non-collinear antiferromagnet

In this study, it was observed that, in non-collinear IrMn3, both the non-magnetic spin Hall effect (NMSHE) and the magnetic spin Hall effect (MSHE) exhibit oscillations as the triangularly ordered magnetic moments of IrMn3 evolve with temperature. These oscillations are strongly influenced by the magnetic properties at the interface between IrMn3 and the adjacent material. Permalloy (Py), a ferromagnet, and platinum (Pt), a paramagnet, were employed as adjacent layers. Such experimental analyses demonstrate the pioneering nature of this phenomenon, which is validated through magnetoresistance measurements performed under different experimental conditions.
