Microscopic foundation for orbitronics: orbital exchange interactions, orbital-dependent transport, and orbital switching
Hantao Zhang, Ran Cheng
Recent experiments highlighted the essential role of the orbital degrees of freedom underlying current-induced magnetic dynamics. However, a microscopic picture of how orbital angu…
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…
