Abstract
Neutron diffraction measurements have been performed on ErRu 2Ge 2 at low temperatures. The compound crystallise in the tetragonal ThCr 2Si 2-type crystal structure (space group I4/mmm). ErRu 2Ge 2 is antiferromagnetic below T N=4.9 K. In the temperature range 1.5–3.4 K the erbium magnetic moments form a square-modulated structure described by the propagation vectors k 1=(k x, 0, 0) and k 2=(3k x, 0, 0) , where k x =0.2174(3). About 3.4 K the magnetic order turns on to be of a sine-wave modulated type. In both phases, the magnetic moments are parallel to the b-axis.
