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…
Thermal effects in spin torque switching of perpendicular magnetic tunnel junctions at cryogenic temperatures
Laura Rehm, Georg Wolf, Bartek Kardasz +4
Temperature plays an important role in spin torque switching of magnetic tunnel junctions causing magnetization fluctuations that decrease the switching voltage but also introduce…
Precessional spin-torque dynamics in biaxial antiferromagnets
Arun Parthasarathy, Egecan Cogulu, Andrew D. Kent +1
The Néel order of an antiferromagnet subject to a spin torque can undergo precession in a circular orbit about any chosen axis. To orient and stabilize the motion against the effec…
Spin transport in an insulating ferrimagnetic-antiferromagnetic-ferrimagnetic trilayer as a function of temperature
Yizhang Chen, Egecan Cogulu, Debangsu Roy +6
We present a study of the transport properties of thermally generated spin currents in an insulating ferrimagnetic-antiferromagnetic-ferrimagnetic trilayer over a wide range of tem…
First harmonic measurements of the spin Seebeck effect
Yizhang Chen, Debangsu Roy, Egecan Cogulu +3
We present measurements of the spin Seebeck effect (SSE) by a technique that combines alternating currents (AC) and direct currents (DC). The method is applied to a ferrimagnetic i…
