  Rare-earth-rich tellurides: Gd4NiTe2 and Er5M2Te2 (M=Co, Ni)

  摘要：

  Three new rare earth metal-rich compounds, Gd4NiTe2, and Er5M2Te2 (M = Ni, Co), were synthesized in direct reactions using R, R3M, and R2Te3 (R = Gd, Er; M = Co, Ni) and single-crystal structures were determined. Gd4NiTe2 is orthorhombic and crystallizes in space group Pnma with four formula units per cell. Lattice parameters at 110(2) K are a = 15.548(9), b = 4.113(2), c = 11.7521(15) Angstrom Er5Ni2Te2 and Er5Co2Te2 are isostructural and crystallize in the orthorhombic space group Cmcm with two formula units per cell.. Lattice parameters at 110(2) K are a = 3.934(l), b = 14.811(4), c = 14.709(4) Angstrom, and a = 3.898(1), b = 14.920(3), c = 14.889(3) Angstrom, respectively. Metal-metal bonding correlations were analyzed using the empirical Pauling bond order concept. Angstrom 2004 Elsevier Inc. All rights reserved.

  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 investigations of magnetization processes for Er3Ni and Er3CO single crystal compounds are presented. The magnetization processes are discussed on the basis of magnetic structures determined previously by neutron diffraction for both compounds. It is shown that both ferromagnetic and antiferromagnetic exchange interactions as well as strong local ionic anisotropy of erbium atoms play a significant role in the magnetization processes forming.

  The Er3CO compound with orthorhombic crystal structure has been investigated by means of magnetic susceptibility, magnetization, electrical resistivity and heat capacity measurements which were made for the first time on single crystalline samples. Below 13.8 K this compound exhibits a complex noncollinear ferromagnetic structure which results from the low symmetry crystalline electric field that surpasses the exchange interaction. Using the magnetization and magnetoresistance measurements along the main crystallographic directions, a complicated and anisotropic magnetization process was revealed. The variation of the electrical resistivity of Er3CO with the temperature is discussed assuming an influence of spin fluctuations rising from f-d exchange interactions. (C) 2002 Elsevier Science B.V.

  Specific heat measurements were performed in wide temperature range T = 2-300 K for the R3Co (R = Er-Gd, Y) compounds. Using values of the Sommerfeld coefficient and Debye temperature estimated for Y3Co compound, the Debye temperatures, phonon and conduction electron contributions as well as magnetic contribution to the specific heat were estimated for all other R3Co compounds.
