  Mn5−xFexGe3 金属间化合物的晶体和磁性研究

  摘要：

  摘要 采用X射线、中子衍射、磁力计和穆斯堡尔效应方法研究了Mn 5− x Fe x Ge 3 金属间化合物。发现x = 1化合物的晶体结构为D8 8 型，而x = 3、4和5化合物的结构为B8 2 型。所有都是具有共线有序原子自旋的铁磁体。晶格常数来自 X 射线衍射图，而磁力测量产生居里温度和魏斯常数以及铁磁和顺磁状态下每个分子的磁矩值。Fe 和 Mn 原子在两个非等效晶位中的分布是用中子衍射方法确定的，并由穆斯堡尔效应测量证实。

  日期：2009.1

  The isothermal section of the phase diagram of the Dy-Fe-Ge ternary system at 773 K has been investigated mainly by X-ray powder diffraction (XRD), with the aid of differential thermal analysis (DTA) and optical microscopy (OM). Sixteen binary compounds have been confirmed. Five ternary compounds DyFe(4)Ge(2), DyFe(2)Ge(2), DyFe(6)Ge(6), Dy(117)Fe(52)Ge(112), and Dy(5)Fe(2)Ge(10) have been confirmed in this system at 773 K.

  The isothermal section of the phase diagram of the Gd-Fe-Ge ternary system at 773 K was investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and optical microscopy. The existences of 14 binary compounds, GdFe(2), GdFe(3), Gd(6)Fe(23), Gd(2)Fe(17), Fe(3)Ge, Fc(5)Ge(3), Fe(6)Ge(5), FeGe, FeGe(2), Gd(5)Ge(3),Gd(5)Ge(4), GdGe,Gd(2)Ge(3), Gd(3)Ge(5), and four ternary compounds GdFe(2)Ge(2), GdFe(6)Ge(6), Gd(2)FeGe(4), Gd(117)Fe(52)Ge(112), were confirmed. This section consists of 21 single-phase regions, 43 two-phase regions, and 23 three-phase regions. (C) 2007 Published by Elsevier B.V.
• Structure, hyperfine interactions and magnetization studies of mechanically alloyed Fe50Ge50 and Fe62Ge38

  X-ray diffraction, Mossbauer spectroscopy and magnetization measurements were used to study the structure and some magnetic properties of Fe50Ge50 and Fe62Ge38 prepared by mechanical alloying from the elemental powders. In both cases in the early stages of milling the intermediate paramagnetic FeGe2 phase was formed. The mechanical alloying process of Fe50Ge50 resulted in the formation of the paramagnetic FeGe (B20) phase with an average crystallite size of about 15 nm. In the case of the Fe62Ge38, the ferromagnetic Fe5Ge3 (beta) phase with a Curie temperature of about 430 K was obtained. The average crystallite size was about 9 nm. The average hyperfine magnetic field of about 16 T allowed it to determine that more than four germanium atoms exist in the nearest environment of the Fe-57 isotopes in the Fe5Ge3 phase.

• Neutron diffraction and 57Fe Mössbauer study of the HfFe6Ge6-type RFe6Ge6 compounds (R=Sc, Ti, Zr, Hf, Nb)

  日期：2000.3

  Both neutron diffraction experiments and Fe-57 Mossbauer measurements have been performed on powder samples of the HfFe6Ge6-type RFe6Ge6 compounds (R = Sc, Ti, Zr, Hf, Nb). These compounds are characterized by an antiferromagnetic stacking along the c-axis of ferromagnetic (001) Fe planes, the easy-direction of magnetization being along [001]. However, for R = Ti, Zr and Nb, we observe that, at 4.2 K, approximate to 30% of iron atoms have moments which deviate from the c-axis. Both the ordered magnetic moment and the hyperfine held on iron atoms are found to increase with the R valency. This observation is tentatively attributed to an increase of the hybridization of the d valence states of the R metal with the 3d iron states. (C) 2000 Elsevier Science Ltd. All rights reserved.
