  SmCu2 的低温 X 射线衍射、传输特性、比热、热膨胀和磁性研究

  摘要：

  已经研究了正交晶系 SmCu2 的各种物理特性（低温 X 射线衍射、电阻率、热导率、热电势、比热、热膨胀和磁化率）。已经观察到 J=5/2 Hund 基态的显着贡献。从热膨胀实验中获得的整体晶体场分裂的估计值为 110 K。磁熵表明双基态，因为观测值 (Sm=5.50+or-0.2 J mol-1 K-1 ) 非常接近理论 R ln 2。在电阻率和磁化率结果中可以看到 J=7/2 多重峰的额外影响。在磁振子热导率的框架内讨论了磁有序区域（尼尔温度 TN = 23 K）中热导率的显着增加。

• Magnetic Properties of Polycrystalline PrCu₂: A Quadrupolar Transition Material
  作者：Jesús Rodríguez Fernández

  DOI：10.1515/znb-2007-0711

  日期：2007.7.1

  Polycrystalline PrCu₂, which has a quadrupolar transition at 7.7 K, has been investigated using electrical resistivity, magnetization and dilatometry techniques. To study dilution effects, two solid solutions of PrCu₂, (Pr_0.8La_0.2)Cu₂, and (Pr_0.8Y_0.2)Cu₂, were also studied. The quadrupolar transition decreases in temperature with doping, while it increases slightly with the magnetic field. In resistivity and thermal expansion, the magnetic contributions show a clear evidence of crystal field excitations. The analysis of both properties provided benchmark values of the Debye temperature and Grüneisen parameters.

  摘要 利用电阻率、磁化和稀释测量技术研究了在 7.7 K 时具有四极转变的多晶 PrCu2。为了研究稀释效应，还研究了 PrCu2 的两种固溶体：(Pr0.8La0.2)Cu2 和 (Pr0.8Y0.2)Cu2。四极转变的温度随掺杂量的增加而降低，但随磁场的增加而略有上升。在电阻率和热膨胀方面，磁性贡献显示了晶体场激发的明显证据。对这两种特性的分析提供了德拜温度和格鲁尼森参数的基准值。

  variety of physical properties (low-temperature X-ray diffraction, electrical resistivity, thermal conductivity, thermopower, specific heat, thermal expansion and susceptibility) of orthorhombic SmCu2 have been studied. A significant contribution of the J=5/2 Hund ground state has been observed. An estimation of the overall crystal-field splitting obtained from the termal expansion experiment yields

• Lattice dynamics of YCu2

  The lattice dynamics of the orthorhombic YCu2 compound has been studied by inelastic neutron scattering on a single crystal. An axially symmetric Born-von Karman model was applied to fit the neutron data. Ab initio calculations of the lattice dynamics at the Gamma-point provided important additional information for the Born-von Karman fit procedure. The calculated phonon density of states was compared with time-of-flight experiments on powdered YCu2 sample material. The experimental studies were completed by Raman experiments and measurements of specific heat, thermal expansion, and compressibility. (C) 2002 Elsevier Science B.V. All rights reserved.
• Interaction of hydrogen with RECu2 and RE(Cu,Ni)2 intermetallic compounds (RE=Y, Pr, Dy, Ho)

  Hydrogenation of RECu2 (RE=Dy, Ho, Y) at room temperature and pressures of 100-1500-bar H, has not resulted in the formation of ternary hydrides. The interaction of hydrogen with Pr(Cu1-xNix)(2) (x=0, 0.1, 0.17, 0.25, 0.32) at room temperature and pressure of 25 bar resulted in the formation of Pr(Cu1-xNix)(2)H-similar to3 hydrides. It was found that the PrCu2H3 and Pr(Cu0.9Ni0.1)(2)H-2.9 hydrides are poorly crystallized, but that an increase of the Ni-content leads to improved crystallinity of the hydrides. The hydrides Pr(Cu0.75Ni0.25)(2)H-similar to3 and Pr(Cu0.68Ni0.32)(2)H-similar to3, preserve, shortly after the hydrogen absorption, the CeCu2 type structure of their metallic matrix with a hydrogen induced volume expansion up to 28% compared to the parent compound. During long-term exposure in the air they undergo a structural transformation from the orthorhombic CeCu2 to the hexagonal Fe2P type with a hydrogen induced volume expansion up to 16.6% compared to the parent compound.
