  CeCu5非弹性中子散射和比热容的测量

  摘要：

  摘要 通过在 10、80 和 300 K 温度下测量金属间化合物 CeCu 5 中的非弹性中子散射，已经推导出晶体电场 (CEF) 参数 B 2 = 1.76 meV 和 B 4 = -2.36 ·10 -2 meV . 在 0.3 到 8 K 温度范围内的比热容在 3.1 K 处表现出异常，这归因于反铁磁相变。巨大的电子比热系数 γ = 120 mJmolK 2 显示了 4f- 和传导电子态的显着混合。

  A study of the magnetic properties of the hexagonal compound CeCu5 reveals antiferromagnetic order below TN=3.9 K. The magnetic structure comprises moments along the c-axis with a propagation vector k=(0,0, 1/2 ). The presence of the Kondo interaction reduces the magnitude of the moments from about 0.42 mu B, expected for a mod +or- 1/2 ) doublet, to about 0.36 mu B, observed from elastic neutron scattering

  The specific heat study of the hexagonal intermetallic compound CeNi5 revealed a substantial Sommerfeld coefficient of the linear electronic term gamma = 40 mJ/mol K-2. When substituting Cu instead of Ni, the electronic term is no longer linear and the low-temperature enhancement of the electronic term becomes apparent. With the increasing Cu concentration the enhanced gamma reaches 46, 95 and 700 mJ/mol K-2 for x = 0.3, 0.4 and 0.5, respectively, in zero magnetic field. When further increasing the Cu concentration a broad peak develops on the c/T vs. T plot below T = 2 K which can be described by a quasi-doublet with the splitting of the energy levels Delta approximate to 4K. The low-temperature electronic specific heat of the Ce(Ni1-xCux)(5) compounds and its behaviour in magnetic fields is discussed in terms of possible Ce-valence fluctuations. (c) 2005 Elsevier B.V.

  The binary Ce-Cu system has been re-investigated via the selected eighteen key alloys by means of the differential scanning calorimetry (DSC), X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy dispersive X-ray analysis techniques. Five intermetallic compounds, Cu6Ce, Cu5Ce, Cu4Ce, Cu2Ce, and CuCe, have been confirmed. Cu6Ce and Cu2Ce melt congruently at 947 degrees C and 810 degrees C, respectively. Cu5Ce, Cu4Ce, and CuCe are formed through peritectic reactions, L + Cu6Ce <-> Cu5Ce at 799 degrees C, L + Cu5Ce <-> Cu4Ce at 792 degrees C, and L + Cu2Ce <-> CuCe at 492 degrees C, respectively. Three eutectic reactions, L <-> (Cu) + Cu6Ce at 879 degrees C, L <-> Cu4Ce + Cu2Ce at 753 degrees C, and L <-> CuCe + (gamma Ce) at 407 degrees C, have been observed. One catatectic reaction, (delta Ce) <-> L + (gamma Ce) at 702 degrees C, was determined. According to the present experimental results, the Ce-Cu phase diagram is revised. (C) 2011 Elsevier B.V.

  The phase relations of the ternary system Ce-Al-Cu in the Cu-poor part at 503 K were investigated by X-ray powder diffraction (XRD). The investigated composition region consists of 16 single-phase, 32 two-phase and 17 three-phase regions. At 503 K, the maximum solid solubilities of Cu in Al, alpha-Ce3Al11, CeAl3 and CeAl2 are about 2.5 at.%, 1.6, 3.6 and 5.3, respectively, and Al in CeCu5 is about 39.2 at.% The homogeneity ranges of Al2Cu and AlCu phases extend from about 32.1 to 32.6 at.% Cu and 49.7 to 52.4 at.% Cu, respectively. Five ternary compounds and their solid solutions have been observed in this work: CeAl12-xCux (4.0 <= x <= 4.52), Ce2Al17-xCux (6.50 <= x <= 7.55), CeAl13-xCux (6.62 <= x <= 6.92), CeAl4-xCux (0.74 <= x <= 1.10) and CeAlCu.
