Article Synopsis
- The study investigates how electrical pulses affect the Néel vector in ultrathin CoO/Pt bilayers to uncover the antiferromagnetic switching mechanism.
- Unexpectedly, the spin Hall magnetoresistance signal changes (either increases or decreases) based on the current density applied, indicating a complex response to electrical pulses.
- By utilizing XMLD-PEEM imaging, the research highlights distinct changes in antiferromagnetic domain structure due to current application, revealing that both local and distant areas from the pulse exhibit different spin switching behaviors, likely driven by a spin-orbit torque mechanism.
We unravel the origin of current-induced magnetic switching of insulating antiferromagnet/heavy metal systems. We utilize concurrent transport and magneto-optical measurements to image the switching of antiferromagnetic domains in specially engineered devices of NiO/Pt bilayers. Different electrical pulsing and device geometries reveal different final states of the switching with respect to the current direction.
