Néel spin-orbit torques arise due to charge currents in some antiferromagnets, and have sparked interest as a possible pathway for achieving electrical control of antiferromagnetic order. While the driving of antiferromagnetic order by Néel spin-orbit torques is now experimentally well established, the inverse process, where magnetic excitations in an antiferromagnetic drive a charge current is not reported. Here Huang, Liao, Qiu, and coauthors observe this inverse process in an Mn2Au thin film.
