Antiferromagnetic domain walls in Sr2IrO4 migrate at supersonic speeds via purely electronic mechanism

Using laser pump-probe coherent X-ray diffraction imaging, researchers directly measured antiferromagnetic domain wall motion in Sr2IrO4 at 100 K and found velocities of 3×10⁶ m/s — far exceeding acoustic (sound) velocities in the material. This supersonic migration is attributed to a purely electronic spin reorientation mechanism that decouples from the lattice, suggesting antiferromagnetic order can be manipulated on femtosecond timescales without significant lattice heating or phonon coupling.
