We have used time-of-flight (TOF) neutron powder diffraction, and both
57
Fe and
119
Sn
Mössbauer spectroscopy over the temperature range 2–600 K to determine the magnetic
ordering mode of the Fe sublattice in YFe6Sn6. The crystal structure is orthorhombic
(space group Immm). The Fe sublattice orders antiferromagnetically with a Néel
temperature of 558(5) K. The TOF neutron diffraction patterns obtained at 4 and 293 K
show that the antiferromagnetic ordering of the Fe sublattice is along [100] with a
propagation vector q=[010]. The magnetic space group is IPm′m′m′. This magnetic
structure is confirmed by our
119 Sn Mössbauer spectra
