Abstract
Spin waves in antiferromagnets are linearly or circularly polarized. Depending on the polarization, traversing spin waves alter the staggered field in a qualitatively different way. We calculate the drift velocity of a moving domain wall as a result of spin wave mediated forces, and show that the domain wall moves in opposite directions for linearly and circularly polarized waves. The analytical results agree with a micromagnetics simulation of an antiferromagnetic domain wall driven by a localized and alternating magnetic field.
