Dislocation-templated antiferromagnetic domains in epitaxial NiO
Alexandra Fonseca Montenegro, Justin Michel, Fengyuan Yang +1
Controlling antiferromagnetic domains is essential for spintronics, yet deterministic manipulation remains challenging due to their lack of net magnetization. Here, we utilize scan…

Sub-Nanosecond Electrical Pulse Switching of an Easy Plane Antiferromagnetic Insulator
Justin J. Michel, Jose Flores, Fengyuan Yang
Electrical switching of antiferromagnets (AFM) is critical for AFM spintronics. However, electrical pulse-induced Neel vector reorientation in AFM insulators, while predicted to oc…

Coherent Spin Pumping Originated from Sub-Terahertz Néel Vector Dynamics in Easy Plane α-Fe2O3/Pt
Gregory Fritjofson, Atul Regmi, Jacob Hanson-Flores +5
We present a thorough study of spin-to-charge current interconversion in bulk and thin films of (0001) α-Fe2O3 /Pt heterostructures by means of all-optical polarization-controlled…
