  摘要：

  摘要 斜方晶系化合物 LSn 2 (SG: Cmcm; L = Tb–Tm) 的磁性结构已通过中子衍射研究确定。化合物 LSn 2 (L = Tb、Dy、Ho Er) 在正弦调制结构中的顺序分别低于 26.7、17.2、7.8 和 4.5 K，其特征在于传播矢量 k = (≈0.39, 0, ≈0.41)。分别低于 12.7、5、4.8 和 2 K，这些化合物经历向共线反铁磁结构的转变，其特征在于 Tb 和 Er 的传播矢量 k = (0, 0, 1/2)，k = (1/2, Ho 为 1/2, 0)，Dy 为 k = (1/2, 1/2, 1/2)。化合物 TmSn 2 在正弦调制结构中低于 4.0 K，其特征在于传播矢量 k = (0, 0.667, 0.380)。对于 L = Tb、Dy、Ho，力矩方向接近 [0 0 1]，对于 L = Er、Tm 沿 [1 0 0] 对齐。

  The phase diagram of the Dy-Ag-Sn ternary system was constructed at 870 K using data of X-ray and partially metallographic analyses. Presence of the DyAgSn starmide in the system was confirmed (ST CaIn2, SG P6(3)/mmc, a = 0.46813(2), c = 0.73433(5) nm) and two new compounds were found: Dy3Ag4Sn4 (ST Gd3Cu4Ge4, SG Immm, a = 0.45316(1), b = 0.72887(2), c = 1.51225(5) nm) and DyAgSn2 (ST Cu3Au, SG Pm-3m, a = 0.453 10(l) nm). The DyAgSn2 is a Curie-Weiss paramagnet in the temperature range 80-470 K (mu(eff) = 10.64 mu(B), theta p = -14 K). A formation of substitutional solid solutions DyAg1-xSnx and DyAg2-xSn, was established. (c) 2006 Elsevier B.V. All rights reserved.

  The structural properties of the compounds in the tin-rich part of the dysprosium-tin system have been studied by X-ray powder diffraction. The crystal structures of six compounds DySn2+x (0 < x < 1) have been characterized. There are four compounds with known structural types: DySn2 with the ZrSi2 structure, Dy3Sn7 with the Gd3Sn7 structure, Dy2Sn5 with the Er2Ge5 structure, DySn3 with the DyGe3 structure and two compounds characterized by new body-centred orthorhombic types (Immm): Dy5Sn11 (a = 4.411 angstrom, b= 42.50 angstrom and c = 4.328 angstrom) and Dy5Sn13 (a = 4.341 angstrom, b = 48.05 angstrom and c = 4.405 angstrom) which result from various insertions of AuCu3 and alpha Po slabs into the ZrSi2 structure. The relationships and structural evolution are discussed. (c) 2007 Elsevier B.V. All rights reserved.
