Abstract
${\mathrm{FeSn}}_{2}$ is a collinear antiferromagnet between ${T}_{N}$=378 K and ${T}_{t}$=93 K as shown by previous neutron diffraction and $^{119}\mathrm{Sn}$ M\"ossbauer studies. Below ${T}_{t}$, two different noncollinear antiferromagnetic structures are consistent with neutron diffraction results, one, called structure I, being canted along with c axis and the other, denoted structure II, being canted in the basal plane (001) along the [110] direction of the chemical cell of ${\mathrm{FeSn}}_{2}$. On the other hand, two magnetic structures canted in the basal plane, ${\mathrm{II}}^{\mathrm{a}}$ and ${\mathrm{II}}^{\mathrm{b}}$, which differ only in the propagation vector agree with $^{119}\mathrm{Sn}$ M\"ossbauer spectra. The simultaneous use of the two techniques has allowed an unambiguous choice of structure ${\mathrm{II}}^{\mathrm{a}}$ which is simply characterized by a combination of the magnetic couplings observed in the high-temperature magnetic structures of ${\mathrm{FeSn}}_{2}$ and ${\mathrm{MnSn}}_{2}$.
