Abstract
The authors show the electrical manipulation of the antiferromagnetic order of a polycrystalline, metallic antiferromagnet via the spin Hall effect in Platinum. The observed electrical response is explained by a thermal activation model assuming an ensemble of uncoupled antiferromagnetic grains. The results suggest that electrical manipulation of the magnetic order via spin-orbit torques is possible in many antiferromagnets without restrictions with respect to crystal quality or material choice.
