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 current-field equivalence ratio of 4x10${}^{-11}$ T A${}^{-1}$ m${}^2$. The N'{e}el vector final state $(𝐧\perp 𝐣)$ is in line with a thermomagnetoelastic switching mechanism for a negative magnetoelastic constant of the CoO …

通过比较磁场感应和电流感应开关可量化反铁磁CoO / Pt中的有效自旋扭矩

我们在共面绝缘反铁磁CoO / Pt中实现了电流感应切换，具有四倍的面内磁各向异性。这是通过自旋霍尔磁电阻进行电测量的，并通过磁场引起的CoO层的自旋跃迁跃迁进行确认。通过施加电流脉冲和磁场，我们可以对作用在电流上的转矩的效率进行量化，并估算出电流场等效比例为4x10${}^{-11}$ TA${}^{-\mathrm{1个}}$ 米${}^2$。N'{e} el向量最终状态$（𝐧\perp 𝐣）$ 与用于CoO的负磁弹性常数的热磁弹性转换机制相一致。
