High-speed antiferromagnetic domain walls driven by coherent spin waves
Kyle L. Seyler, Hantao Zhang, Daniel Van Beveren +4
The ability to rapidly manipulate domain walls (DWs) in magnetic materials is key to developing novel high-speed spintronic memory and computing devices. Antiferromagnetic (AFM) ma…
Characterizing Spin-Orbit Torques by Tensorial Spin Hall Magnetoresistance
Hantao Zhang, Ran Cheng
Magnetoresistance (MR) provides a crucial tool for experimentally studying spin torques. While MR is well established in the device geometry of the spin Hall effect (SHE), as exemp…
Néel Spin-Orbit Torque in Antiferromagnetic Quantum Spin and Anomalous Hall Insulators
Junyu Tang, Hantao Zhang, Ran Cheng
Interplay between magnetic ordering and topological electrons not only enables new topological phases but also underpins electrical control of magnetism. Here we extend the Kane-Me…
Anisotropic Field Suppression of Morin Transition Temperature in Epitaxially Grown Hematite Thin Films
Haoyu Liu, Hantao Zhang, Josiah Keagy +5
We have demonstrated the existence of the Morin transition in epitaxially grown hematite thin films exceeding a critical thickness. The Morin transition temperature can be suppress…
Voltage-Controlled Magnetoelectric Devices for Neuromorphic Diffusion Process
Yang Cheng, Qingyuan Shu, Albert Lee +13
Stochastic diffusion processes are pervasive in nature, from the seemingly erratic Brownian motion to the complex interactions of synaptically-coupled spiking neurons. Recently, dr…
