Efficient Spin Torques in Antiferromagnetic CoO/Pt Quantified by Comparing Field- and Current-Induced Switching
Original language description
We achieve current-induced switching in collinear insulating antiferromagnetic CoO=Pt, 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 currentfield equivalence ratio of 4 × 10−11 TA−1 m2. The N´eel vector final state ðn⊥jÞ is in line with a thermomagnetoelastic switching mechanism for a negative magnetoelastic constant of the CoO.
