The effects of current induced Néel spin-orbit torques on the antiferromagnetic domain structure of epitaxial Mn2Au thin films were investigated by X-ray magnetic linear dichroism -photoemission electron microscopy (XMLD-PEEM). We observed current induced switching of AFM domains essentially corresponding to morphological features of the samples. Reversible as well as irreversible Néel vector reorientation was obtained in different parts of the samples and the switching of up to 30 % of all domains in the field of view of 10 µm is demonstrated. Our direct microscopical observations are compared to and fully consistent with anisotropic magnetoresistance effects previously attributed to current induced Néel vector switching in Mn2Au. PACS numbers:In antiferromagnetic (AFM) spintronics the staggered magnetization, or more precisely the Néel vector describing the spin structure, can be used to encode information [1][2][3]. For the switching of the Néel vector and the read-out of its orientation different strategies have been pursued [4]. The Néel vector was e. g. manipulated by an exchange-spring effect with a ferromagnet (FM) and read-out via tunneling anisotropic magnetoresistance (T-AMR) measurements [5,6]. Other experiments were based on a ferromagnet to AFM phase transition [7] or on strain induced anisotropy modifications [8]. However, for antiferromagnetic spintronics Néel vector switching by current-induced spin-orbit torques (SOTs) [9], whose FM counterparts are already established for memory applications [10,11], are most promising due to superior scaling, switching speed and device compatibility.The SOTs used for FM spintronics are typically generated at interfaces with heavy metals [12,13]. However, a specific crystallographic structure with oppositely broken inversion symmetry on the each of the collinear AFM sublattices makes Mn 2 Au and CuMnAs up to now the only known antiferromagnets, for which a so called bulk Néel spin-orbit torque (NSOT) [14] can enable current induced Néel vector manipulation in a single layer system. Indeed, this was demonstrated experimentally for CuMnAs [15,16] and, more recently, for Mn 2 Au [17][18][19] as well.Whereas in the case of CuMnAs, the modification of the AFM domain structure by current pulses was observed directly by X-ray magnetic linear dichroism -photoelemission electron microscopy (XMLD-PEEM) [16,20], such microscopic insights are missing for Mn 2 Au up to now. However, direct imaging of the effect of current pulses on the Néel vector orientation is crucial for the interpretation of previously published results of resistivity changes attributed to a Néel vector reorientation in Mn 2 Au [17][18][19]. Furthermore, magnetic microscopy enables the identification of important quantities and mech-anisms of the Néel vector manipulation such as switched volume fraction, morphological influence on the domain pattern, and domain wall motion.In this paper we demonstrate the imaging of current induced modifications of the AFM domain structure of epitaxial Mn 2 Au thin film...
