• Electrical and Hall Resistivity in Rare Earth Intermetallic Compounds RAg_1-<i>x</i>In_<i>x</i> (R: Gd, Tb and Dy)

  The electrical resistivity and the Hall resistivity in polycrystalline specimens of RAg 1- x In x have been measured from 4.2 K to room temperature and the paramagnetic region up to room temperature, respectively. The spin disorder resistivity at 0 K, ρ m (0), takes a maximum near the boundary of the different magnetic structures in each compound system, and that above the Curie temperature, ρ m (∞)

  RAg 1- x In x 多晶样品的电阻率和霍尔电阻率分别在 4.2 K 至室温和顺磁区至室温的范围内测量。自旋无序电阻率在 0 K 时，ρ m (0)，在每个复合系统中不同磁结构的边界附近取最大值，并且在居里温度以上，ρ m (∞)，在 Gd 系统中随 x 增加，而在 Tb 和 Dy 系统中，它在 x = 0.3 附近需要最大值。普通霍尔系数 R 0 对所有化合物都是正的。另一方面，自发霍尔系数 R s 对于除 GdAg 和 TbAg 之外的所有化合物都是负的，并且在所有系统中，当 x ≥ 0.1 时，其大小随 x 增加。已经在局部自旋模型的基础上讨论了结果。

  Abstract The 161 Dy Mossbauer spectra of crystalline and amorphous DyAg were measured between 300 and 4.2 K. The amorphous sample was prepared by sputtering. At low temperatures typical magnetic relaxation spectra are observed in both materials. The main difference is the presence of a smeared out lattice electric field gradient and the slowing down of the relaxation rate in amorphous DyAg. Both effects

  摘要 在 300 和 4.2 K 之间测量了结晶和非晶 DyAg 的 161 Dy Mossbauer 光谱。通过溅射制备非晶样品。在低温下，两种材料都可以观察到典型的磁弛豫谱。主要区别在于存在模糊的晶格电场梯度和非晶 DyAg 中弛豫速率的减慢。这两种效应都是由非晶化过程导致 DyAg 晶格立方对称性的随机局部畸变引起的。

  Abstract Neutron diffraction measurements were performed for an antiferromagnetic compound DyAg with T N =56.7 K. Magnetic structures were found to be the (π π 0)-type at 12 K and rthe sinusoidally modulated transverse static spin wave propagating along the 〈110〉 direction and polarized in the 〈001〉 direction at 50.7 K.

  日期：2004.8

  The standard enthalpies of formation of some lanthanide silver compounds have been measured by high temperature direct synthesis calorimetry at 1373 +/- 2 K. The following results (in kJ/mol of atoms) are reported: 1: 1 composition-AgTb (-36.5 +/- 2.9); AgDy (-37.3 +/- 1.8); AgEr (-44.9 +/- 3.2); AgTm (-43.0 +/- 2.3); 2:1 composition-Ag2Pr (-24.7 +/- 1 1.6); Ag2Nd (-21.8 +/- 1.9); Ag2Gd (-23.9 +/- 1.6); Ag2Tb (-22.7 +/- 1.8); Ag2Dy (-22.3 +/- 2.3); Ag2Ho (-25.0 +/- 2.3); Ag2Er (-24.0 +/- 2.3); Ag2Tm (-24 +/- 3); Ag2Lu (-25.6 +/- 1.9); 3:1 composition-Ag3Tb (-20.6 +/- 2.0); Ag3Dy (-22.8 +/- 1.9); Ag3Ho (-25.1 +/- 2.0); Ag3Er (-25.4 +/- 2.3); Ag3Tm (-20.2 +/- 2.3). The results are compared with the semi-empirical predicted values of Miedema and coworkers and with the values predicted by Gschneidner for lanthanide alloys. They are also compared with the enthalpies of formation of the Au-LA systems by the present authors. (C) 2003 Elsevier B.V. All rights reserved.

  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.
