  Magnetic and transport properties of TmB12, ErB12, HoB12 and DyB12

  摘要：

  We present measurements of the magnetization and electrical resistivity of TmB12, ErB12 and HoB12 singlecrystalline samples as well as of a DyB12 polycrystalline sample. Data were taken in the paramagnetic state as well as in the magnetically ordered regime. To our knowledge, this is the first systematic investigation of TmB12, ErB12, HoB12 and DyB12 on the magnetically ordered phase by measurements of magnetization and electrical resistivity. All samples investigated undergo antiferromagnetic ordering in the lower Kelvin temperature range. From the magnetization data, the Neel temperatures, the paramagnetic Curie temperatures, and the effective magnetic moments of the corresponding rare earth ions are determined. It is shown that the indirect exchange interaction of RKKY type is the dominating mechanism leading to the observed antiferromagnetic ordering. The measured temperature dependences of the electrical resistivity show a pronounced effect of superzone boundaries near Neel temperatures. The spin wave scattering of conduction electrons below T-N is discussed, too. (C) 1999 Elsevier Science B.V. All rights reserved.

• Determination of tetragonal-cubic phase boundary of ZrRO (R = Nd, Sm, Y, Er and Yb) BY Raman scattering

  Abstract Existing phases of arc-melted ZrO2-X mol%RO1.5 specimens were investigated mainly by Raman spectroscopy, which is sensitive to the phase transition induced by the oxygen displacements (0≤X≤24) R = Nd, Sm, Y, Er and Yb). The tetragonal and monoclinic phases coexisted at X = 2 and 4 for R = Nd, Y, Er and Yb, and at X = 2 for R = Sm. Tetragonal single phase is obtained in the specimens with higher

  摘要 电弧熔化 ZrO2-X mol%RO1.5 试样的现有相主要通过拉曼光谱进行研究，拉曼光谱对氧位移引起的相变敏感 (0≤X≤24) R = Nd, Sm, Y,呃和Yb）。对于 R = Nd、Y、Er 和 Yb，四方相和单斜晶相在 X = 2 和 4 处共存，对于 R = Sm，在 X = 2 处共存。在具有较高含量的试样中获得四方单相。轴比ca随着RO1.5含量的增加而降低，在RO1.5含量为14或16mol%时趋于一致。470 cm-1 附近的拉曼峰强度是四方相的特征，随着 RO1.5 含量的增加而降低。由拉曼散射确定的立方-四方相界位于约 X = 18-19 mol%，与掺杂剂种类 R 无关。轴比ca为1的四方相出现在约X=16mol%处。相界的组成位置几乎与掺杂物质 R 无关。
• Temperature-Dependent Rate Constants for the Reactions of Gas-Phase Lanthanides with O₂

  The reactivity of the gas-phase lanthanide atoms Ln (Ln = La-Yb with the exception of Pm) with O-2 is reported. Lanthanide atoms were produced by the photodissociation of [Ln(TMHD)(3)] and detected by laser-induced fluorescence. For all the lanthanides studied with the exception of Yb, the reaction mechanism is bimolecular abstraction of an oxygen atom. The bimolecular rate constants (in molecule(-1) cm(3) s(-1)) are described in Arrhenius form by k[Ce((1)G(4))] = (3.0 +/- 0.4) x 10(-10) exp(-3.4 +/- 1.3 kJ mol(-1)/RT); Pr(I-4(9/2)), (3.1 +/- 0.7) x 10(-10) exp(-5.3 +/- 1.5 kJ mol(-1)/RT); Nd(I-5(4)), (3.6 +/- 0.3) x 10(-10) exp(-6.2 +/- 0.4 kJ mol(-1)/RT); Sm(F-7(0)), (2.4 +/- 0.4) x 10(-10) exp(-6.2 +/- 1.5 kJ mol(-1)/RT); EU(S-8(7/2)), (1.7 +/- 0.3) x 10(-10) exp(-9.6 +/- 0.7 kJ mol(-1)/RT); Gd(D-9(2)), (2.7 +/- 0.3) x 10(-10) exp(-5.2 +/- 0.8 kJ mol(-1)/RT); Tb(H-6(15/2)), (3.5 +/-. 0.6) x 10(-10) exp(-7.2 +/- 0.8 kJ mol(-1)/RT); Dy(I-5(8)), (2.8 +/- 0.6) x 10(-10) exp(-9.1 +/- 0.9 kJ mol(-1)/RT); Ho(I-4(15/2),), (2.4 +/- 0.4) x 10(-10) exp(-9.4 +/- 0.8 kJ mol(-1)/RT); Er(H-3(6)), (3.0 +/- 0.8) x 10(-10) exp(-10.6 +/- 1.1 kJ mol(-1)/RT); Tm(F-2(7/2)), (2.9 +/- 0.2) x 10(-10) exp(-11.1 +/- 0.4 kJ mol(-1)/RT), where the uncertainties represent +/-2 sigma. The reaction barriers are found to correlate to the energy required to promote an electron out of the 6s subshell. The reaction of Yb(S-1(0)) with O-2 reacts through a termolecular mechanism. The limiting low-pressure third-order rate constants are described in Arrhenius form by k(0)[Yb(S-1(0))] = (2.0 +/- 1.3) x 10(-28) exp(-9.5 +/- 2.8 kJ mol(-1)/RT) molecule(-2) cm(6) s(-1).
