Néel spin-orbit torques can occur in antiferromagnets with broken inversion symmetry, such as Mn2Au, and have garnered significant interest recently, as they allow for the electrical control of the antiferromagnetic ordering. Here, Behovits et al. apply intense terahertz electric fields to Mn2Au and observe the deflection of the Néel vector on ultrafast time scales due to Néel spin-orbit torques.
