Abstract Using antiferromagnets as active elements in spintronics requires the ability to manipulate and read-out Néel vector orientation. Here we demonstrate for Mn 2 Au, a good conductor with high ordering temperature suitable applications, reproducible switching using current pulse generated bulk spin-orbit torques by magnetoresistance measurements. Reversible consistent changes of longitudinal resistance planar Hall voltage star-patterned epitaxial Au(001) thin films were densities ≃10 7 A/cm . The symmetry agrees theoretical predictions large effect more than ≃6% is reproduced ab initio transport calculations.
