Current pulse driven switching mechanisms in antiferromagnetic Mn₂Au — •Jonathan Bläßer¹, Sonka Reimers¹, Yuran Niu², Evangelos Golias², Francesco Maccherozzi³, Miriam Fischer¹, Guzmán Orero Gámez¹, Mathias Kläui¹, and Martin Jourdan¹ — ¹Johannes Gutenberg-Universität, Mainz, Germany — ²MAX IV Laboratory, Lund, Sweden — ³Diamond Light Source, Chilton, Didcot, Oxfordshire, UK

In antiferromagnetic spintronics, reorientation of the staggered magnetization driven by current pulses can originate from different mechanisms. Investigating Mn₂Au, for longer pulses [Rei23] the thermal contribution is dominant. However, for pulses in the nanosecond range Néel spin-orbit torque switching is demonstrated.
