Abstract
We achieve current-induced switching in collinear insulating antiferromagnetic , with fourfold in-plane magnetic anisotropy. This is measured electrically by spin Hall magnetoresistance and confirmed by the magnetic field-induced spin-flop transition of the CoO layer. By applying current pulses and magnetic fields, we quantify the efficiency of the acting current-induced torques and estimate a current-field equivalence ratio of . The Néel vector final state is in line with a thermomagnetoelastic switching mechanism for a negative magnetoelastic constant of the CoO.
