      abstract     = {In antiferromagnetic spintronics, the read-out of the
                      staggered magnetization or Néel vector is the key obstacle
                      to harnessing the ultra-fast dynamics and stability of
                      antiferromagnets for novel devices. Here, we demonstrate
                      strong exchange coupling of Mn2Au, a unique metallic
                      antiferromagnet that exhibits Néel spin-orbit torques, with
                      thin ferromagnetic Permalloy layers. This allows us to
                      benefit from the well-established read-out methods of
                      ferromagnets, while the essential advantages of
                      antiferromagnetic spintronics are only slightly diminished.
                      We show one-to-one imprinting of the antiferromagnetic on
                      the ferromagnetic domain pattern. Conversely, alignment of
                      the Permalloy magnetization reorients the Mn2Au Néel
                      vector, an effect, which can be restricted to large magnetic
                      fields by tuning the ferromagnetic layer thickness. To
                      understand the origin of the strong coupling, we carry out
                      high resolution electron microscopy imaging and we find that
                      our growth yields an interface with a well-defined
                      morphology that leads to the strong exchange coupling.},
