Neutron diffraction study of the magnetic order in NdMn2Ge1.6Si0.4

Here we report a detailed investigation of NdMn 2 Ge 1.6 Si 0.4 ; this forms part of our investigation of the magnetic order across the NdMn 2 Ge 2âˆ’ x Si x (x = 0â€“2.0) series by magnetometry, x-ray diffraction and neutron diffraction over the temperature range 6â€“465 K. On decreasing the temperature from 465 K, NdMn 2 Ge 1.6 Si 0.4 exhibits four magnetic transitions: (i) from paramagnetism to intralayer antiferromagnetism AFl at T Intra N ~ 430 K; (ii) AFl to canted ferromagnetism Fmc at T Inter C ~ 330 K; (iii) Fmc to conical magnetic ordering of the Mn sublattice Fmi at T cc ~ 178 K and (iv) Fmi(Mn) to Fmi(Mn)+F(Nd) at T Nd C ~ 72 K.
