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…
