  RCu6(R=La, Ce, Pr, Nd, Sm, Gd, and Th)化合物的低温电学和磁学特性

  摘要：

  摘要 系统地研究了具有 RCu6 型结构的二元化合物的电阻率和磁化率的温度依赖性，以讨论结构不稳定性、传输和磁性能。含 Pr、Nd、Sm 和 Gd 的化合物在高温下显示出游离稀土离子的典型居里-魏斯顺磁性，而 Nd、Sm 和 Gd 化合物在低温下的磁序由电阻率和磁化率测量的尖端。在大约 0.2K 的 ThCu6 中观察到超导转变。在高于 60mK 的 LaCu6 和 CeCu6 中既没有磁序也没有超导性。此外，系统 (Ce1-xPrx)Cu6 与系统 (Ce1-xLax)Cu6 进行了比较和对比。

  The binary Cu-Sm system is one of the basic sub-systems, necessary for the development of the materials used as permanent magnets. Nonetheless, there can be found numerous inconsistencies in the phase equilibria data for the system. The current work deals with the evaluation of the phase stabilities of the intermetallic phases in the system and phase equilibria in the Cu-Sm system with the DTA, SEM/EPMA

  二元 Cu-Sm 系统是基本子系统之一，是开发用作永磁体的材料所必需的。尽管如此，系统的相平衡数据仍存在许多不一致之处。目前的工作涉及使用 DTA、SEM/EPMA 和XRD 方法评估系统中金属间相的相稳定性和 Cu-Sm 系统中的相平衡。已发现Cu 6 Sm和Cu 5 Sm表现出一些均匀性范围。已证实 CuSm 是通过包晶反应形成的，而不是通过全等熔化形成的。更新的相平衡数据总结在新版本的 Cu-Sm 相图中。发现 Cu 6 Sm 相的硬度为 335 ± 29 HV。

  The phase diagrams of the Sm-Ni-Pb and Sm-Cu-Pb systems were constructed using X-ray phase analysis. Four ternary compounds SmNiPb (TiNiSi structure type, space group Pnma, a=7.3199(3) Angstrom, b=4.5769(2) Angstrom, c=7.8015(3) Angstrom), Sm2Ni2Pb (Mn2AlB2 structure type, space group Cmmm, a=4.087(1) Angstrom, b=14.187(3) Angstrom, c=3.716(1) Angstrom), Sm5NiPb3 (Hf5CuSn3 structure type, space group P6(3)/mcm, a=9.171(2) Angstrom, c=6.710(1) Angstrom) and Sm12Ni6Pb (Sm12Ni6In structure type, space group Im3, a=9.825(2) Angstrom) exist in the Sm-Ni-Pb system. Two ternary compounds SmCuPb (LiGaGe structure type, space group P6(3)mc, a=4.5965(2) Angstrom, c=7.4769(2) Angstrom) and Sm5CuPb3 (Hf5CuSn3 structure type, space group P6(3)/mcm, a=9.316(1) Angstrom, c=6.6881(4) Angstrom) exist in the Sm-Cu-Pb system.

  The isothermal section of the Sm-Cu-Mg system at 670 K was studied in the 0-50 at.% Mg concentration range. The phase analysis was carried out by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), wavelength dispersive spectrometry (WDS) and X-ray powder diffraction (XRPD) techniques. The X-ray single crystal and powder analysis were used for structure investigations. Of the nine ternary phases (tau(1)-tau(9)) which were found to exist in this section are seven new phases, tau(1) - Sm60.1Cu26.4Mg13.5, tau(3) - Sm22.5Cu74.3Mg3.2, tau(4) - SmCu4Mg, tau(5) - SmCuMg, tau(6) -SmCuMg2, tau(7) - Sm81.2Cu10.3Mg8.5 and tau(8) - Sm4Cu10Mg3, and two known phases, tau(2) - Sm2Cu2Mg and tau(9) - SmCu9Mg2. As the result of our investigation the crystal structures of tau(2), tau(4), tau 5, tau 6 and tau 8 phases have been established. Moreover, it has been found that the solubility of Mg and Cu in Sm-Cu and Sm-Mg binary phases, respectively, is insignificant, and that the maximum solubility takes place in the case of Cu2Mg phase, which dissolves up to 5 at.% Sm.

• Heavy fermion characteristics in amorphous SmCu6 alloy
  作者：H. Okajima、K. Sumiyama、Y. Homma、T. Hihara、K. Suzuki

  日期：1995.2

  The amorphous SmCu6 alloy produced by sputter-deposition reveals a heavy fermion character: the electronic specific heat coefficient is about 0.3 J mol(-1) K-2. Broad peaks at around 3.8 K in the specific heat and magnetic susceptibility (chi), and the hysteresis in the chi between zero-field-cooled and field-cooled specimens demonstrate a spin-glass ordering at low temperatures.
