The structure and magnetic properties of NdMn2-xCu xGe2 (0.0≤x≤1.0) were studied by X-ray powder diffraction and magnetization measurements. All compounds crystallize in the ThCr2Si2-type structure with space group I4/mmm. Substitution of Cu for Mn leads to a linear decrease in the lattice constant c and the unit cell volume V and a linear increase in the lattice constant a. Increasing substitution of Cu for Mn shows a depression of ferromagnetic ordering. The observed phase transitions are summarized in a magnetic x-T phase diagram and compared with previous neutron diffraction results for x = 0.0. © 2003 Elsevier B.V. All rights reserved.
