论文摘要
我们通过在适应的Kerr显微镜中执行并发传输和磁光学成像测量，证明了NIO/PT中Nio/PT中的大面积（$> 100 \;μm^2 $）的稳定和可逆的电流诱导的转换。通过在这些电流诱导的开关实验中，通过将防铁磁性结构域的变化和磁通信号响应相关联，我们将磁性磁性和非磁性贡献对传输信号做出了贡献。我们的桌面方法建立了一个可靠的程序，可以减去传输信号中的非磁性贡献，并提取与抗磁磁性结构域切换相关的旋转磁磁敏感响应，从而使一个人可以从简单的传输测量中推断出抗磁性切换的细节。
We demonstrate stable and reversible current induced switching of large-area ($> 100\;μm^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.
