a Atomic and chiral-spin structures in a kagome plane of the NCAFM D019-Mn3Sn. The blurred color denotes the atoms and magnetic moments in the neighboring kagome plane. b Schematic of the electrical mutual switching in Mn3Sn/Mo/CoFeB. Red, blue, and gray arrows denote the magnetic orientations of Mn3Sn, CoFeB, and non-equilibrium spins with z-component, respectively. NM: nonmagnetic material. c Out-of-plane X-ray diffraction result in a Ru(2 nm)/Mn3Sn(30 nm)/MgO(1.3 nm)/Ru(1 nm) stack. A large thickness of Mn3Sn is used here in order to obtain clear signal. d Optical image of a Hall bar device, which is connected to a current source and a voltmeter for transport measurements. e \({R}_{{{\rm{H}}}}-{H}_{z}\) loops of Mn3Sn/Mo/CoFeB/MgO (black) and Mn3Sn/Mo/MgO (red). The inset shows the zoomed-in region around the switching of CoFeB. f Magnetization M as a function of the in-plane magnetic field \({\mu }_{0}{H}_{x}\) in the same stack of (c).
