a Schematic of the spin structure. Blue and Red spins represent Mn atoms in Kagome planes. Purple sphere represents the Sn atom. The direction of the octupole moment is along [2-1-10]. b Schematic of canted Kagome AFM. All the spins titled to the direction of the octupole moment c Periodic spin canting effect in Mn3Sn crystals. d XRD spectra of Mn3Sn on Al2O3 substrate. e Phi scan of the Mn3Sn substrate, which indicates the four-fold symmetry. f Crystal structure of Mn3Sn, showing the atomic positions of Mn and Sn within the unit cell. g Atomic configuration of Mn and Sn atoms viewed along the [0001] direction in the Mn₃Sn crystal structure. h High-resolution TEM image of Pt/Mn3Sn films. i FFT of TEM images of Mn₃Sn thin films.
