  Isothermal cross-section of the Ce–Pd–Ge phase diagram at 600°C

  摘要：

  The interaction of the components in the Ce-Pd-Ge system at 600 degrees C was investigated over the whole concentration range by X-ray powder and monocrystal diffraction, metallography, and X-ray microprobe analysis. The formation of the previously reported phases, CePdGe and CePd2Ge2, was confirmed and 15 new ternary compounds were observed. The crystal structures of the compounds Ce2PdCe6, Ce(Pd,Ge)(2), Ce3Pd20Ge6, CePd2Ge, Ce7Pd4Ge2 and CePd5Ge3 were determined. (C) 1998 Elsevier Science S.A.

  Ce–Mn–Ge system deserves particular attention because the phase equilibria are complex. Relative to the previously reported phase diagram evaluated at a lower temperature (400 °C), three ternary phases (CeMn 2 Ge 2 , Ce 2 MnGe 6 , and CeMnGe) persist, Ce 2 MnGe 5 does not form, and two new phases with very close composition (Ce 3 Mn 2 Ge 3 and Ce 43 Mn 18 Ge 39 ) appear at 800 °C. Ce 3 Mn 2 Ge 3 (orthorhombic

  摘要 通过粉末 X 射线衍射和能量色散 X 射线分析检查了四元 Ce-Mn-In-Ge 相图的一部分。发现了两个新的四元（Ce 4 Mn 2 InGe 4 和Ce 2 Mn 2 InGe 2 ）和两个三元（Ce 3 Mn 2 Ge 3 和Ce 43 Mn 18 Ge 39 ）相。边界三元系统（Ce-Mn-In、Mn-In-Ge、Ce-In-Ge 和 Ce-Mn-Ge）的等温截面在 800 °C 下确定。其中，Ce-Mn-Ge 系统值得特别关注，因为相平衡是复杂的。相对于先前报道的在较低温度 (400 °C) 下评估的相图，三个三元相（CeMn 2 Ge 2 、Ce 2 MnGe 6 和 CeMnGe）仍然存在，Ce 2 MnGe 5 没有形成，两个新相与非常接近的成分（Ce 3 Mn 2 Ge 3 和Ce 43 Mn 18 Ge 39 ）出现在800 °C 时。Ce 3 Mn 2 Ge 3

  the crystal structures, and the electronic structures of two new tetragonal phases, La5Ge3 and Ce5Ge3. Both title compounds crystallize in the Pu5Rh3 (P4/ncc) structure type, which has close structural relationship with the W5Si3 (I4/mcm) structure type. The synthetic results, supported by thermal analysis suggest that this tetragonal phase is only stable at relatively low temperature and it transforms

  报道了两种新四方相 La5Ge3 和 Ce5Ge3 的合成、晶体结构和电子结构。两种标题化合物均以 Pu5Rh3 (P4/ncc) 结构类型结晶，这与 W5Si3 (I4/mcm) 结构类型具有密切的结构关系。由热分析支持的合成结果表明，这种四方相仅在相对较低的温度下稳定，并在 850°C 以上转变为六方形式（Mn5Si3 结构类型，P63/mcm）。还讨论了 La5Ge3（Pu5Rh3 型）和 La5Sn3（W5Si3 型）之间的结构关系。温度相关的直流磁化强度和电阻率测量表明，四方相 La5Ge3 表现出类似泡利的顺磁性，是一种良好的金属导体。对于四方相 ，磁行为在高温状态下服从居里-魏斯定律，而在低温下则偏离居里-魏斯定律。没有观察到低至 5 K 的长程磁序，尽管可以推断出低于约 5 K 的短程相关性。50 K。 的电阻率测量也显示出类似金属的温度依赖性，尽管类似于

  Magnetic and transport properties of Ce5Ge3 and La5Ge3 have been studied. The magnetic susceptibility of Ce5Ge3 above 90 K is fitted with a Curie-Weiss law with an effective paramagnetic moment of 2.66 mu(B) and a paramagnetic Curie temperature of - 30.9 K. Arrott plot shows that Ce5Ge3 has a spontaneous magnetization below 6.4 K. The magnetization curve shows large hysteresis with remanent magnetic moment of 0.24 mu(B) and coercive field of 1.2 kOe at 2.0 K. The magnetization at 1.9 K reaches 0.9 mu(B)/Ce at 145 kOe and saturation behavior is not found even at this high field. The temperature dependence of the magnetic resistivity indicates that Ce5Ge3 can be classified as a dense Kondo system. (C) 1999 Elsevier Science B.V. All rights reserved.
