Unidirectional Spin Hall Magnetoresistance in Antiferromagnetic Heterostructures
Yang Cheng, Junyu Tang, Justin J. Michel +4
Unidirectional spin Hall magnetoresistance (USMR) has been widely reported in the heavy metal / ferromagnet (HM/FM) bilayer systems. We observe the USMR in the Pt/α-Fe2O3 bilayers…
Third Harmonic Characterization of Antiferromagnetic Heterostructures
Yang Cheng, Egecan Cogulu, Rachel D. Resnick +4
Electrical switching of antiferromagnets is an exciting recent development in spintronics, which promises active antiferromagnetic devices with high speed and low energy cost. In t…
Quantifying Spin-Orbit Torques in Antiferromagnet/Heavy Metal Heterostructures
Egecan Cogulu, Hantao Zhang, Nahuel N. Statuto +4
The effect of spin currents on the magnetic order of insulating antiferromagnets (AFMs) is of fundamental interest and can enable new applications. Toward this goal, characterizing…
Direct Imaging of Electrical Switching of Antiferromagnetic Néel Order in -FeO 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/-FeO Hall bars us…
Electrical Switching of Tristate Antiferromagnetic Néel Order in -FeO Epitaxial Films
Yang Cheng, Sisheng Yu, Menglin Zhu +2
The ability to manipulate antiferromagnetic (AF) moments is a key requirement for the emerging field of antiferromagnetic spintronics. Electrical switching of bi-state AF moments h…
