Schematics of the induced anisotropy in the measurement in Figure 5b. The cooling field BFClies in the x–z plane as shown in the top figure. The film plane is in the x–y plane and it is shown in each kagome plane configuration. The orange arrows in each kagome plane represent the direction and size of the effective magnetic field Beff, which is the projection of the cooling field BFCon the kagome plane. The green arrows represent the direction and size of the induced anisotropy or bias field Bexin Mn3Sn. In configuration (i–iii), three representative kagome plane orientations are shown. n vector represents the normal vector of the kagome plane, and it is parallel to the y-axis, z-axis, and x-axis in configuration (i–iii), respectively.
