It is shown that the spin current, polarized along the anisotropy axis, excites the conical precession of the Néel vector in such domain wall, which allows obtaining a reliable alternating current output signal, in contrast to the planar precession in a homogeneous uniaxial antiferromagnet, where alternating current generation is difficult to achieve. A new method of visualization of the direction of the Néel vector using spin moment microscopy with submicron spatial resolution is proposed. Using the developed method and ab-initio calculations, it has been shown that in Mn2Au there is a violation of the symmetry of antiferromagnetic pairing.
