The magnetic structures of GdCuSn, GdAgSn and GdAuSn

We have determined the magnetic structures of GdCuSn, GdAgSn and GdAuSn using a combination of 155Gd Mössbauer spectroscopy and neutron powder diffraction. Each compound shows the same antiferromagnetic ordering of the Gd sublattice. The magnetic cell is doubled along the crystallographic a-axis (pr...

Summary:We have determined the magnetic structures of GdCuSn, GdAgSn and GdAuSn using a combination of 155Gd Mössbauer spectroscopy and neutron powder diffraction. Each compound shows the same antiferromagnetic ordering of the Gd sublattice. The magnetic cell is doubled along the crystallographic a-axis (propagation vector k=[12,0,0]) with the moments aligned along the hexagonal c-axis, forming alternating ferromagnetic sheets of up/down Gd moments along the a-axis.
