  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。

  Gd(Ni1−xCox)3金属间化合物的磁性和磁热效应

  摘要：

  摘要 在本文中，我们介绍了多晶 Gd(Ni 1− x Co x ) 3 金属间化合物的磁性能。Co原子部分取代Ni导致居里温度TC升高。还表明所检查样品的饱和磁化强度随着 Ni/Co 取代度的增加而单调降低。根据磁等温线估计具有室温附近 TC 值的几个样品的磁热效应 (MCE)。已观察到与 3d 磁性亚晶格中磁无序增加相关的磁熵减少。

  DOI：10.1143/jpsj.57.3157

  日期：1988.9.15

  The nuclear magnetic resonance of 59 Co nuclei in magnetic domains of GdCo 3 has been measured under external magnetic fields up to 55 kOe at 4.2 K. In order to assign the observed NMR signals to each Co site, the 59 Co nuclear magnetic resonance of Gd(Co 1- x T x ) 3 where T stands for Ni and Fe, has also been measured under the same conditions. The 59 Co hyperfine fields at the 3 b , 6 c and 18 h

  GdCo 3 磁畴中 59 Co 核的核磁共振已在 4.2 K 下高达 55 kOe 的外部磁场下进行测量。 为了将观察到的 NMR 信号分配给每个 Co 位点，Gd 的 59 Co 核磁共振(Co 1- x T x ) 3 其中T代表Ni和Fe，也在相同条件下测量。GdCo 3 中3 b、6 c 和18 h 位点的59 Co 超精细场分别测量为80 kOe、-58 kOe 和-80 kOe。还从核磁共振和中子衍射数据中讨论了对 YCo 3 中 Co 原子磁矩的轨道贡献。

  日期：2007.3

  A portion of the isothermal section (1173 K) of the phase diagram of the Gd-Co-Al ternary system (up to 33.3 at.% Gd) were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. Fourteen single-phase regions (including solid solution regions of the binary compounds), twenty-five two-phase regions and twelve three-phase regions were found to exist at this isothermal section. In the GdCo2-GdAl2 system, the existence of the GdCo0.74Al1.26 phase is identified and it has a composition range of 30-45 at.% Al, the maximum solid solubility of Al in GdCo, is about 15 at.%, and Co in GdAl2, is about 16 at.%. Besides, the maximum solid solubility of Al in Co, Gd2Co17 and GdCo5 is about 6, 17 and 25 at.%, respectively, the maximum solid solubility of Gd in Co, CoAl is below 2 at.% and the solid solubility range is from 47 to 61 at.% Al in CoAl phase. In this work, no new ternary compounds were observed. (c) 2006 Elsevier B.V. All rights reserved.

  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.
