A major advantage of antiferromagnets for applications is the lack of stray fields and insensitivity to magneto-electric perturbations, however, this also makes electric control of AFMs challenging. Here, focusing on a non-collinear AFM, Mn3Ge/Sn, Wu et al demonstrate fast domain wall motion, with remarkably low current density, and extend our understanding of spin-transfer torques that drive this to noncollinear antiferromagnetic systems.
