  We demonstrate stable and reversible current induced switching of large-area
($> 100\;\mu m^2$) antiferromagnetic domains in NiO/Pt by performing concurrent
transport and magneto-optical imaging measurements in an adapted Kerr
microscope. By correlating the magnetic images of the antiferromagnetic domain
changes and magneto-transport signal response in these current-induced
switching experiments, we disentangle magnetic and non-magnetic contributions
to the transport signal. Our table-top approach establishes a robust procedure
to subtract the non-magnetic contributions in the transport signal and extract
the spin-Hall magnetoresistance response associated with the switching of the
antiferromagnetic domains enabling one to deduce details of the
antiferromagnetic switching from simple transport measurements.
