The magnetic structure of a weak ferromagnetic Mn 3 Sn has been studied by polarized neutron diffraction at room temperature. Large flipping ratios were observed for the 100 and 110 reflections under application of a magnetic field in the c -plane perpendicular to the scattering vector. The spin structure deduced from the h 0 l and h h l reflections has a triangular configuration but the spin plane is not determined. For applied field parallel to [010] the spin-A is parallel to [010], but for applied field parallel to [110] the spin-B is antiparallel to [110]. The magnetic form factor of the Mn atom agrees with the calculated Mn 2+ form factor and the magnetic moment is 1.78 µ B /Mn.
