with and without Hubbard U correction for on-site Coulomb interactions reveals the true …

Controlling chiral domain walls in antiferromagnets using spin-wave helicity

A Qaiumzadeh, LA Kristiansen, A Brataas - Physical Review B, 2018 - APS
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 …
