Published on 2026-09-11 by Yiyue Wang, Wenbo Zhang, Hao-Hsuan Chen, Milad Jalali, Andrea Meo and Yaowen Liu @IOP SCIENCE

Abstract: Antiferromagnets offer a promising platform for ultrafast spintronic emitters owing to their intrinsic terahertz ( ) spin dynamics, yet the mechanisms governing the onset and coherence of current-driven oscillations remain poorly understood. Here we develop a multiscale theoretical framework for the collinear antiferromagnet Mn2Au driven by a perpendicularly polarized spin current. Using a momentum-dependent canonical transformation of the coupled macrospin Hamiltonian, we show that the emergenc[...]
