Direct Imaging of Electrical Switching of Antiferromagnetic Néel Order in $\alpha$-Fe${}_2$O${}_3$ Epitaxial Films

Egecan Cogulu, Nahuel N. Statuto, Yang Cheng +4

We report the direct observation of switching of the Néel vector of antiferromagnetic (AFM) domains in response to electrical pulses in micron-scale Pt/$\alpha$-Fe${}_2$O${}_3$ Hall bars us…
