Controlling chiral domain walls in antiferromagnets using spin-wave helicity — •Alireza Qaiumzadeh, Lars Kristiansen, and Arne Brataas — Center for Quantum Spintronics, Department of Physics, Norwegian University of Science and Technology, NO-7491 Trondheim, Norway

In antiferromagnets, the Dzyaloshinskii-Moriya interaction lifts the degeneracy of left- and right-circularly polarized spin waves. This relativistic coupling increases the efficiency of spin-wave induced domain-wall motion. In this talk, we report a fast all-magnonic helicity-dependent antiferromagnetic domain wall motion in the presence of the Dzyaloshinskii-Moriya interaction.
