  ErCo3-氢化物和TmCo3-氢化物的磁化研究

  摘要：

  摘要 ErCo 3 和TmCo 3 化合物是亚铁磁性的，居里温度分别为401 K和370 K。它们吸收氢以形成 ErCo 3 H 4.3 和 TmCo 3 H 3.3 。从对这些以及其他 RCo 3 氢化物在 4.2 到 300 K 温度区间内的磁化研究，推断氢吸收导致钴的磁矩降低和 R-Co 相互作用减弱（R = 稀土）。除了 GdCo 3 -氢化物的情况外，在高达 21 kOe 的外加场中，在 4.2 K 时未达到磁化饱和。这暗示了扇形稀土时刻的可能性。早先用 R = Gd、Dy 和 Ho 研究的 RCo 3 -氢化物以及 ErCo 3 -氢化物和 TmCo 3 -氢化物在室温下似乎都是磁性有序的。

  The isothermal section of the phase diagram of the Gd-Dy-Co ternary system at 800 K was investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA), optical microscopy and scanning electron microscopy (SEM) techniques. The result shows that this section consists of 9 single-phase regions and 9 two-phase regions, and 1 three-phase region. The compounds Gd2Co17 and Dy2Co17, Gd2Co7 and Dy2Co7, GdCo3 and DYCo3, GdCo2 and DYCo2, Gd12Co7 and Dy12Co7, Gd3Co and Dy3Co form a continuous series of solid solutions. In addition, the single phases alpha-Gd and alpha-Dy also form a continuous series of solid solution. The maximum solid solubility of Dy in Gd4Co3 is about 10.8 at.%. The binary compounds Dy4Co3, GdCo5 and DyCo5 were not observed at 800 K. No ternary compound was found. (c) 2006 Published by Elsevier B.V.

  The isothermal section of the phase diagram of the Tb-Dy-Co ternary system at 773 K was investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscope (SEM). The result shows that this section consists of 9 single-phase regions and 8 two-phase regions, and no three-phase region. The compounds Tb2Co17 and Dy2Co17, Tb2Co7 and Dy2Co7, TbCo3 and DyCo3, TbCo2 and DyCo2, Tb4Co3 and Dy4Co3, Tb12Co7 and Dy12Co7. Tb3Co and Dy-3 CO form a continuous series of solid solutions. The single phases Th and Dy also form a continuous solid solution. The binary compounds TbCo5 and DyCo5 were not observed at 773 K. No ternary compound was found. In addition, we experimentally determined the vertical section of pseudobinary system and magnetic property of Tb1-xDyxCo2 (x from 0 to 1) series alloys, T-c decreases and the maximum magnetic entropy change |Delta S-M.max| increases with the increase of Dy content. The Arrott plots and the change of |Delta S-M.max| show that magnetic phase transition from second-order to first-order occurs with the increase of Dy content between x = 0.6 and 0.8.

  Phase equilibria were established in the Dy-Co-V ternary system at 773 K by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM). The result shows that the isothermal section consists of 13 single-phase regions, 23 two-phase regions and 12 three-phase regions. The maximum solid solubilities of V in (Co), Dy2Co17, DyCo3, DyCo2, Dy12Co7 and Dy3Co are about 6.5,10.0, 2.0, 6.3, 1.5 and 5.0 at.% V, respectively. It is found that there is some homogeneity range in the only ternary compound of DyCo12-xVx With x= 1.6-3.8 at 773 K. There is no solubility of V in Dy2Co7 observed at 773 k. The binary compounds Dy4Co3 and DyCo5 are not observed at 773 K. (C) 2009 Published by Elsevier B.V.
• Magnetic behaviour of γ-phase hydrides RCo3H∼4 in high magnetic fields

  High-field magnetization measurements have been carried out for single-crystal gamma-phase hydrides RCo3H(approximately 4) with R = Th and Dy and for powder samples with R = Nd and Gd. The results indicate that these gamma-phase hydrides with R = Y, Ho and Er become antiferromagnetic except for R = Gd at low temperatures due to the appearance of a negative Co-Co intersublattice interaction. A metamagnetic transition of the Co-sublattice magnetization occurs from the antiferromagnetic to the forced ferromagnetic state if the field is applied along the c-axis. GdCo3H(approximately 4), being ferrimagnetic at low temperatures, becomes antiferromagnetic above 32 K. The significant weakening of the R-Co interaction due to hydrogenation leads to a Neel temperature of about 200 K in all hydrides and an almost independent behaviour of the R and Co sublattices in the compounds with R = Nd, Ho and Er. The role of the R-Co interaction in the magnetic behaviour of the hydrides is discussed.
