119Sn Mössbauer studies of the DyAgSn and DyAuSn compounds

X-ray diffraction, magnetic susceptibility measurements and 119Sn Mössbauer spectroscopy were used to study the intermetallic DyAuSn and DyAgSn compounds. It was shown that both compounds order antiferromagnetically at low temperatures. The Dy magnetic moments are normal to the hexagonal c-axis in DyAuSn and are inclined at an angle of 45° to this axis in DyAgSn. The occurrence of a magnetic hyperfine field distribution in DyAgSn suggests that this compound crystallizes in the disordered CaIn2-type of structure.
