  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.
