18.08.2022 Joint Publication about the electron structure in Mn2Au

A joint publication with Libor Šmejkal about the parity violations of the electronic structure in the antiferromagnet Mn2Au has been published in Journal of Physics: Condensed Matter.

They perform momentum resolved photemission on individual antiferromagnetic domains. The results show an asymmetry of the energy with respect to momentum. The responsible spin–orbit interaction couples the broken parity to the Néel order parameter direction. With this foundation they 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.
