- Abstract
- Using momentum microscopy with sub-<i>µ</i>m spatial resolution, allowing momentum resolved photoemission on individual antiferromagnetic domains, we observe an asymmetry in the electronic band structure,E(k)≠E(-k), in Mn<sub>2</sub>Au. 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,<b>N</b>, by combining spatially resolved momentum microscopy with<i>ab-initio</i>calculations that correlate the broken parity with the vector<b>N</b>.
