Abstract
Powder neutron diffraction measurements have been carried out on RCuSb2 (R = Dy and Ho) compounds at low temperatures. These compounds crystallize in a tetragonal ZrCuSi2-type structure and are antiferromagnets with the Neel temperatures equal to 6.4 K (R = Dy) and 4.5 K (R = Ho). At 1.5 K the magnetic order of DyCuSb2 can be described by the propagation vector k = (0, 0.119, 0.521). At the same temperature the magnetic order in HoCuSb2 is described by three propagation vectors: k(1) = (0, 0.465, 0.260), k(2) = (0, 0.408, 0.770) and k(3) = (0, 0, 0.519). With increasing temperature the structure described by k(1) disappears about 3.5 K while the two other structures described by k(2) and k(3) are stable up to the Neel temperature. The Dy and Ho magnetic moments form a sine-wave modulated structure in the basal plane. (C) 2004 Elsevier B.V All rights reserved.
