Crystal and magnetic structure and magnetic properties for deuteride HoNiSnD0.67 are provided on the basis of high-resolution powder X-ray and neutron diffraction and magnetometric data. This deuteride crystallises with the hexagonal ZrNiAl type related structure and is antiferromagnetic below the Neel temperature equal to 2.6(3) K. The deuterium atoms occupy the tetrahedral 4h Ho3Ni sites. At 2 K Ho magnetic moments form a sine-modulated magnetic structure described by the propagation vector K(= 0.34, 0.34, 0.117). The Ho magnetic moment, equal to 5.36 mu(B), lies in the basal plane (001). (c) 2005 Elsevier B.V. All rights reserved.
