Abstract

Antiferromagnets (AFMs) are promising for future spintronic applications because of their fast dynamics and lack of stray fields. For the required switching of the Néel vector (staggered magnetization), a current induced bulk Néel spin-orbit torque (NSOT) is most promising. Here we demonstrate current pulse induced complete, remanent, and reversible Néel vector switching of epitaxial Mn2Au(001) thin films. A current polarity dependence demonstrates an NSOT acting on AFM domain walls. We correlate direct imaging of the Néel vector reorientation by x-ray photoemission electron microscopy with measurements of the associated anisotropic magnetoresistance [1].
