Fig. 1: structure of Mn3Pt film.
a Out-of-plane theta to 2theta XRD spectra of Mn3Pt at different planes. b Phi scan patterns of Mn3Pt at (111) plane and the corresponding MgO substrate. c The magnetization data was measured at 300 K with the magnetic field paralleled to the c–axis. The spin structure of cubic Mn3Pt is shown in the inset (the red sphere denotes Pt atom, the blue sphere and arrow denote Mn atom and spin direction, respectively. Mn atoms at the Kagome planes have different scalar spin chirality under different magnetic fields. d High-resolution cross-sectional scanning transmission electron microscopy (STEM) images of Mn3Pt/MgO. The bright regions correspond to the Mn3Pt monolayers. The scale bar is 1 nm. e High–resolution STEM image of the basal plane of the Mn3Pt. Blue and yellow dots represent the Pt atom and the Mn atom, respectively. The scale bar is 1 nm. f Selected–area electron diffraction (SAED) patterns of Mn3Pt obtained by transmission electron microscopy (TEM).
