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.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
