a–c \({R}_{{{\rm{H}}}}-I\) measurements performed in various conditions. Shared conditions of neighboring figures are shown in a legend between the figures. Current range dependence of RH, where the absolute value of the maximum current at positive side, I+ is smaller (larger) than that of the minimum current at negative side, I- in (a, b). CoFeB initialization dependence of RH, where CoFeB is initialized along –z (+z) in (b, c). d In-plane magnetic field \({\mu }_{0}{H}_{x}^{{{\rm{meas}}}}\) dependence of \({I}_{-}\)-biased (left) and \({I}_{+}\)-biased (right) loops. \({\mu }_{0}{H}_{x}^{{{\rm{meas}}}}\) varies from −10 to +10 mT with a step of 2 mT. The switching magnitude \(\Delta {R}_{{{\rm{H}}}}\) is qualitatively described by a scaling arrow with a colored gradient. e Switching ratio of the loops shown in (d) and the difference δ between \({I}_{-}\)-biased and \({I}_{+}\)-biased loops. f tMo dependence of δ at zero magnetic field. The error bars in (e, f) indicate the standard deviation errors in five continuous rounds of measurements. g Key factors of the Mn3Sn switching, where \({H}_{y}^{{{\rm{Oe}}}}\) is an Oersted field along y direction. h Schematic for the switching process of Mn3Sn. Red arrows indicate the net magnetization representing the overall magnetic order of Mn3Sn. Orange arrows denote the effective rotation direction of the net magnetization of Mn3Sn under spin injection. Green arrows denote the rotation of the net magnetization of Mn3Sn driven by the Oersted field.
