  • Investigation of phase equilibria in the quaternary Ce–Mn–In–Ge system and isothermal sections of the boundary ternary systems at 800 °C

    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.

    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

    compound undergoes a crystallographic transition at low temperature. Two different tetragonal phases coexist at room temperature for the compound CeGe1.2Si0.475. These observations are related to phase transformations previously observed in silicides and to the frequent ordering of vacancies in the lattice of rare earth silicides and germanides.
    摘要 研究了Ce-Si-Ge系固溶体的一些晶体学性质。在化合物 CeGe0.66Si0.92 中观察到一种新型超结构,其中富含硅或锗的平面交替出现;该化合物在低温下发生结晶转变。对于化合物 CeGe1.2Si0.475,两种不同的四方相在室温下共存。这些观察结果与先前在硅化物中观察到的相变以及稀土硅化物和锗化物晶格中空位的频繁排序有关。

    Synthesis and structural characterization of the new compounds R2Zn1–xGe6 (R = La–Nd, Sm, Gd–Ho) is reported. A structural change was revealed along this series by careful analysis of single-crystal X-ray diffraction data. For light rare earths up to Tb the orthorhombic oS72-Ce2(Ga0.1Ge0.9)7 model was established; instead, the Dy compound represents a new structure type (P21/m, mP34, Z = 4, a = 7.9613(3)

  • Magnetic properties of the CeGe1−xSix series studied by powder neutron diffraction and μSR-measurements
    作者:P. Schobinger-Papamantellos、M. Kenzelmann、A. Schenck、F.N. Gygax、K.H.J. Buschow、C. Ritter

    The antiferromagnetic ordering in orthorhombic (Pnma) CeGe1-xSix pseudobinary series was studied by powder neutron diffraction and muSR measurements. The ordering temperature varies linearly between 10.4 K for CeGe and 6.1 K for CeSi. The magnetic phase diagram comprises two distinct regions of magnetic ordering as a function of Si concentration x, which are characterized by the wave vectors q(1) = (0, 1/2, 0) r.l.u., for 0 less than or equal to x less than or equal to 0.8 and q(2) = (0, 1/2, 1/16) r.l.u. for CeSi. Both structures correspond to collinear arrangements of the Ce moments within the (a, b) plane. The ordered Ce3+ moment value of 1.0(1)mu(B)/atom at 1.5 K of the commensurate q(1) phases as well as the amplitude of the wave of the modulated q(2) phase (1.56(4)mu(B)/atom) are strongly reduced compared to the free Ce3+ ion value gJmu(B) = 2.14mu(B). A harrow field distribution observed with muSR suggests that CeSi has a commensurate square wave magnetic structure, which possibility could not be tested in the neutron work due the unobservability of the expected weak higher harmonics. The temperature dependence of the internal field detected by muSR suggests that the spin interactions are long range in CeSi, but short ranged in CeGe. These results point towards a localized non-Kondo behavior for CeSi and strong hybridization of the 4f electrons with the conduction band for CeGe. (C) 2004 Elsevier.B.V. All rights reserved.
  • Isothermal cross-section of the Ce–Pd–Ge phase diagram at 600°C
    作者:Yu.D. Seropegin、A.V. Gribanov、O.I. Bodak

    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.
