✦ Synopsis

Powder neutron diffraction and magnetic measurements have been carried out on R 2 RhSi 3 (R=Dy, Ho and Er) compounds at low temperatures. These compounds crystallize in a derivative of the hexagonal AlB 2 -type structure and are antiferromagnets with the N! eel temperatures equal to: 6.3 K for R=Dy, 5.2 K for R=Ho and 5 K for R=Er. Below these temperatures the magnetic order is described by the propagation vector: k¼ ð0; 0; 1 2 Þ for R=Dy, k¼ ð 1 2 ; 0; 0Þ for R=Ho and k=(0,0,0) for R=Er. This magnetic order is stable in the temperature range between 1.5 K and the N! eel temperature.
