  Current pulse driven Neel vector rotation in metallic antiferromagnets is one
of the most promising concepts in antiferromagnetic spintronics. We show
microscopically that the Neel vector of epitaxial thin films of the
prototypical compound Mn2Au can be reoriented reversibly in the complete area
of cross shaped device structures using single current pulses. The resulting
domain pattern with aligned staggered magnetization is long term stable
enabling memory applications. We achieve this switching with low heating of 20
K, which is promising regarding fast and efficient devices without the need for
thermal activation. Current polarity dependent reversible domain wall motion
demonstrates a Neel spin-orbit torque acting on the domain walls.
