  Magnetic properties of the hydrides based on R Fe compounds

  摘要：

  The influence of hydrogenation on the magnetic properties of the compounds GdFe3, Gd6Fe23, DyFe3 and Dy6Fe23 has been investigated by measurements of powder high field magnetization at 4.2 K in pulsed fields up to 38 T. The magnetization curves of the hydrides GdFe3Hx and Gd6Fe23Hx show the spin-flip transition from the ferrimagnetic state to a noncollinear spin structure at the critical field B-c. The exchange coupling n(RT) between the R and the Fe sublattices was estimated from the slope dM/dB above B-c. The values of n(RT), B-c and the compensation temperature T-comp decrease with increasing hydrogen composition, indicating a weakening in the R-T coupling. The magnetization of the hydrides DyFe3Hx and Dy6Fe23Hx does not reach saturation even at 38 T. In the Dy hydrides the magnetocrystalline anisotropy for the Dy ion competes with n(RT) which is weakened upon hydrogenation. The fanning effect is revealed by the Dy moments at the ground state of Dy6Fe23H12. The Fe moment increases in the initial stages of absorption of hydrogen and then decreases as more hydrogen is absorbed.

  Abstract A series of Gd-Fe-Cu alloys was prepared to determine the 1073 K isothermal section of the Gd-Fe-Cu system through the use of the Scanning Electron Microscopy-Energy Dispersive X-ray spectrometry (SEM-EDS) and the X-ray Powder Diffraction (XRD) techniques. Twelve single phase regions, eleven two-phase regions, and ten three-phase regions, as well as two liquid areas were experimentally identified

Intermetallic compounds CeCo 3 , GdFe 3 and CeNi 2 Co have CeNi 3 or PuNi 3 structure type. The maximum compositions of the hydride phases under high pressure CeCo 3 H 6.1 , GdFe 3 H 6.1 and CeNi 2 CoH 5.4 have been calculated on the basis of analysis of absorption–desorption

  multiplet splitting in Fe containing compounds as observed in photoemission the magnetic moment of Fe in GdFe 2 , GdFe 3 , and Gd 2 Fe 17 was determined to be (1.76±0.02)μ B independent of composition. Charge transfer as a cause of this reduction in the Fe moment compared to Fe metal has been excluded. Valence band spectra support a model in which a reduced exchange splitting of the Fe 3d states is responsible

  摘要 利用光电发射中观察到的含铁化合物中的多重分裂，确定了 GdFe 2 、GdFe 3 和 Gd 2 Fe 17 中 Fe 的磁矩为 (1.76±0.02)μ B，与成分无关。与 Fe 金属相比，作为 Fe 矩降低的原因的电荷转移已被排除。价带光谱支持一个模型，其中 Fe 3d 状态的减少交换分裂是造成较小力矩的原因。

  Abstract In this paper, we present crystal structure, electronic structure and magnetic properties of pollicrystalline Gd(Ni1−xFex)3 intermetallic compounds. The rhombohedral PuNi3 type of crystal structure for the whole series was confirmed with the use of X-ray powder diffraction. The partial replacement of Ni by Fe atoms up to x ≤ 0.4 causes the increase in Curie temperature TC and next for 0.4

  The isothermal section (500 degrees C) of the phase diagram of the Gd-Fe-Ga ternary system was investigated by X-ray powder diffraction analysis. Eleven binary compounds, GdGa2, GdGa, Gd3Ga2, Gd5Ga3, GdFe2, GdFe3, Gd2Fe17, Fe3Ga, Fe6Ga5, Fe3Ga4 and FeGa3, have been confirmed. Two ternary compounds, GdFe5.3Ga6.7 and GdFe5Ga7, were found in this ternary system at 500 degrees C. The compound GdFe5.3Ga6.7 is orthorhombic ScFe6Ga6-type structure (space group Immm) with a = 0.8567 (9), b = 0.86960 (9) and c = 0.50782 (5) nm, while the compound GdFe5Ga7 is tetragonal ThMn12-type structure (space group 14/mmm) with a = 0.8651(1) and c = 0.50934 (6) nm. The isothermal section at 500 degrees C consists of 16 single-phase regions, 31 two-phase regions and 16 three-phase regions. The maximum solid solubilities of Ga in GdFe2, GdFe3, Gd2Fe17 are 9.2, 9.0, and 44.3 at.% respectively The homogeneity range of GdGa2 is from 22 to 33.3 at.% Ga in Gd-Ga side but the solid solubility of Fe in this compound is very small. The homogeneity range of GdFe5Ga7 is from 53.8 to 59.2 at.% Ga. Very limited solid solutions were measured in the other compounds. (c) 2008 Elsevier B.V. All rights reserved.
