摘要：

Neutron powder diffraction and magnetic measurements have been carried out on RCx Ge-2 (R = Ho, Er) compounds. Both compounds crystallize in the orthorhombic CeNiSi2-type structure (space group Cmcm) and they are antiferromagnets with the Neel temperature equal to 4.5 K for R = Er and 8.0 K for R = Ho. Neutron diffraction measurements indicate the presence of collinear magnetic structures of the G, mode in HoCu0.33Ge2 and G(x) mode in ErCu0.25Ge2. (C) 2004 Elsevier B.V. All rights reserved.
