  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。

  resistivity and the magnetic susceptibility for binary compounds with the RCu6 — type structure has been systematically investigated to discuss structural instabilities, transport and magnetic properties. The Pr, Nd, Sm, and Gd-containing compounds reveal a typical Curie-Weiss paramagnetism of free rare earth ions at high temperatures, while magnetic order at low temperature for the Nd, Sm, and Gd compounds

  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.
