Fig. 4: Full sequence of the electrical mutual switching in Mn3Sn/Mo/CoFeB.
From: Electrical mutual switching in a noncollinear-antiferromagnetic–ferromagnetic heterostructure
a Full \({R}_{{{\rm{H}}}}-I\) loop measured in the range of \(-12\;{{\rm{mA}}}\le I\le+12\;{{\rm{mA}}}\) without external magnetic fields. \({I}_{{{\rm{C}}}}^{{{\rm{CoFeB}}}({{\rm{Mn}}}3{{\rm{Sn}}})}\) denotes the critical current for switching CoFeB (Mn3Sn). Mn3Sn and CoFeB are initialized along +x and –z directions by magnetic fields, respectively. b Schematics for the electrical mutual switching between CoFeB and Mn3Sn. Panels (A–J) correspond to the states labeled in (a). Red (blue) and green (purple) dashed rectangles indicate the switched (unswitched) CoFeB domains and the switched (unswitched) Mn3Sn domains, respectively. The blue-boxed unswitched CoFeB domains exist on top of the multi-domain structure of Mn3Sn. Dashed arrows indicate the spin flow pointing from its origin to the target. Yellow curved arrows illustrate the torque acting on the target magnetic moments.
