Title: Profile and dynamics of Antiferromagnetic domain walls under spin-orbit torque
Abstract: Domain walls in antiferromagnets under spin-polarized current present dynamics that is not observed in ferromagnets and it is tunable by the current polarization. Propagating walls are obtained for an in-plane polarization and precessional dynamics is obtained for perpendicular polarization. We obtain the wall velocity by a perturbation method for low velocities, and the wall profile is found to lack a definite parity by perturbation and asymptotic methods. Oscillatory motion of domain walls is obtained for spin polarization that has both perpendicular and in-plane components, and it is found that this comes in two flavors.
