    Direct observation of antiferromagnetic parity violation in the electronic structure of Mn2Au

  • Original language description

    Using momentum microscopy with sub-µm spatial resolution, allowing momentum resolved photoemission on individual antiferromagnetic domains, we observe an asymmetry in the electronic band structure, E(k) ̸= E(−k), in Mn2Au. This broken band structure parity originates from the combined time and parity symmetry, PT , of the antiferromagnetic order of the Mn moments, in connection with spin–orbit coupling. The spin–orbit interaction couples the broken parity to the Néel order parameter direction. We demonstrate a novel tool to image the Néel vector direction, N, by combining spatially resolved momentum microscopy with ab-initio calculations that correlate the broken parity with the vector N.
