Fig. 2

Field dependent magnetization, M(H), loops measured at 5 K with field parallel and perpendicular to the c-axis for (a) Mn3.09Sn0.91, b Mn2.7Fe0.3Sn, and c Mn2.5Fe0.5Sn samples. d Rietveld refinement of the neutron diffraction (ND) pattern at 3 K for Mn2.5Fe0.5Sn. The data were recorded in a neutron wavelength λ = 2.4395 Å. We obtain the fitting parameter Rwp = 11.3 for the Rietveld refinement. The inset shows extracted canting angle at different temperatures. e Simulated powder neutron diffraction patterns corresponding to the out-of-plane canting of spins from the in-plane 120° structure for different canting angles ϕ. f Change in the relative integrated intensity of (200) and (201) peaks with respect to the (102) peak as a function of temperature. Dotted lines serve as a guide to the eye. g Expanded view of the (200) and (201) ND patterns at different temperatures, along with the Rietveld refinement for coplanar and noncoplanar models.
