  Dy 3 Co单晶中磁跃迁的临界行为

  摘要：

  摘要 交流光热电热量计已用于研究 Dy3Co 中磁跃迁的临界行为，测量低温下的热扩散率、比热和热导率。有两个相变，这两个相变都在三个变量中呈现奇点。≈ 42 K 处的反铁磁到顺磁相变符合短程、各向同性普遍性类、3D-海森堡（αexp = -0.13 表示比热，bexp = -0.15 表示热扩散率，αtheor = btheor = -0.134）。在下跃迁的情况下，反铁磁自旋排序在 ≈ 32 K 处重新排列，临界行为显示出与各向同性的偏差。这些结果与文献中已经发现的磁测量有关。

  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.

  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.
