  Metal–semiconductor–insulator transitions in R3Ni compounds induced by hydrogenation

  摘要：

  Electrical resistivity and ac magnetic susceptibility measurements of R3Ni and their hydrides R3NiHx were carried out. It is shown that the conductivity of R3NiHx compounds with a large amount of hydrogen have semiconductor and insulator conductivity type as compared with metallic conduction in the original compounds R3Ni. The resistivity of the original compounds is discussed on the basis of a conduction electron scattering model. Strongly modified transport processes of the hydrides are discussed on basis of a 'hopping' model. (C) 2001 Elsevier Science B.V. All rights reserved.

  增强短程磁相关和金属间化合物中受挫相互作用的存活率

  摘要：

  弹性和非弹性中子散射和磁化测量已被用于研究低于和高于磁有序温度的 R{sub 3}T 化合物（R=Gd、Er、Tb；T=Ni、Co）中磁态的特性。在反铁磁化合物 Gd{sub 3}Ni 和 Tb{sub 3}Ni 高于其磁有序温度时观察到的磁化曲线的明显非布里渊形状，以及早先报道的关于保留对总比热的磁贡献的数据Gd{sub 3}T 和高于磁有序温度的电阻率的异常行为归因于顺磁态在宽温度范围内短程磁相关的存在。通过对 Tb{sub 3}Ni 和 Tb{sub 3}Co 进行的粉末中子衍射测量，已经揭示了短程磁有序的持续性直至温度高于 Neel 温度的 5-6 倍。另一方面，非弹性中子散射的结果表明，低温磁激发在 Tb{sub 3}Co 和 Er{sub 3}Co 中均受到强烈抑制。这表明扩展的短程磁相关性是 R{sub 3}T 型化合物的固有特征，是由于层状晶体结构和几何受挫层内交换之间的差异更多»相互作用和层间交换。«

  diffraction measurements performed for Tbsub 3}Ni and Tbsub 3}Co. On the other hand, results from inelastic neutron scattering show that the low temperature magnetic excitations are strongly suppressed in both Tbsub 3}Co and Ersub 3}Co. It is suggested that the extended short-range magnetic correlations, which turn out to be an inherent feature of Rsub 3}T type compounds, are due to the layered crystal

  The phase diagrams of the Gd-Ni-Pb and Gd-Cu-Pb systems were constructed using X-ray phase analysis. Five ternary compounds GdNiPb (TiNiSi structure type, space group Pnma, a=7.2481(9) Angstrom, b=4.5428(6) Angstrom, c=7.7701(9) Angstrom), Gd2Ni2Pb (Mn2AlB2 structure type, space group Cmmm, a=4.0619(9) Angstrom, b=14.107(2) Angstrom, c=3.6942(9) Angstrom), Gd5NiPb3 (Hf5CuSn3 structure type, space group P6(3)/mcm, a=9.094(1) Angstrom, c=6.6427(7) Angstrom), Gd12Ni6Pb (Sm12Ni6In structure type, space group Im3, a=9.770(2) Angstrom) and Gd6Ni2Pb0.5 (Ho6Co2Ga structure type, space group Immm, a=9.487(1) Angstrom, b=9.673(1) Angstrom., c=10.032(1) Angstrom) exist in the Gd-Ni-Pb system at 870 K.

  Three new rare earth metal-rich compounds, Gd6MTe2 (M = Co, Ni) and Er6RuTe2, were synthesized in direct reactions between the R, R3M, and R2Te3 (R=Gd, Er, M=Co, Ni, Ru). These materials all adopt the same Zr6CoAl2 structure type with space group P (6) over bar 2m (No. 189, Z=1). Single crystal structures of Gd6CoTe2 and Er6RuTe2 were determined and lattice parameters are a=b=8.3799(5), c = 3.9801(4) Angstrom, and a = b = 8.1473(5) Angstrom, c = 3.9962(4) Angstrom, respectively. Gd6NiTe2 was characterized by X-ray powder diffraction; lattice parameters are a = b = 8.412(2), c = 3.9577(9) Angstrom. Metal-metal bonding correlations were analyzed using the empirical Pauling bond order concept. (C) 2003 Elsevier B.V. All rights reserved.
