Abstract

Here we report a detailed investigation of NdMn₂Ge_1.6Si_0.4; this forms part of our investigation of the magnetic order across the NdMn₂Ge_2−xSi_x (x = 0–2.0) series by magnetometry, x-ray diffraction and neutron diffraction over the temperature range 6–465 K. On decreasing the temperature from 465 K, NdMn₂Ge_1.6Si_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.
