  Hydrogen induced structural and magnetic transformations in magnetic regenerator materials ErNin (n=1, 2) and HoCu2

  摘要：

  The effect of hydrogenation on the structures and magnetic properties of magnetic regenerators HoCu2 (CeCu2-type), ErNi2 (MgCu2-type) and ErNi (FeB-type) has been investigated. All these compounds can form crystalline hydrides which remain in the structure of the original compound. In the case of ErNi2, hydrogenation induces volume expansion up to 13% compared with the parent compound. The magnetic moment and the Curie temperature of the crystalline hydrides decreases as the hydrogen content increases. In the case of ErNi and HoCu2, there is a little change in the lattice parameters and magnetic properties of the crystalline hydrides compared with original compounds. Amorphous hydrides are also observed after the hydrogenation of ErNi2 and HoCu2 compounds. (C) 2006 Elsevier B.V. All rights reserved.

  增强过冷稀土金属间化合物 RNi（R = Gd、Ho 和 Er）的磁热效应

  摘要：

  摘要 等原子 RNi（其中 R = Gd、Ho 和 Er）化合物已通过过冷制备​​。磁化数据分别证实了样品在 69 K、35 K 和 10 K (TC) 下的铁磁排序。已根据 TC 附近的等温磁熵变 (ΔSm) 估计磁热效应 (MCE)。对于过冷 RNi (R = Gd, Ho)，TC 附近 50 kOe 场变化的最大 ΔSm 值 (ΔSmmax) 分别约为 -18 Jkg-1K-1、-20 Jkg-1K-1 和 -30 Jkg-1K-1和 Er) 化合物。ΔSmmax 值大于通过电弧熔化和熔纺技术制备的相同化合物获得的值。观察到的过冷样品的 MCE 增强可能是由于纯度的提高导致磁化转变周围磁化强度的更快变化。

  replacing the commercial Pt metal in the hydrogen evolution reaction (HER). In this work, RENi2 and RERu0.25Ni1.75 (RE = Pr, Tb, and Er) were synthesized and their electrocatalytic HER activities were explored. Among undoped compounds, PrNi2 exhibits the best performance and requires an overpotential of 55 mV, while partially replacing Ni with Ru element (PrRu0.25Ni1.75) can greatly reduce the overpotential

  基于过渡金属的金属间化合物是有前途的电催化剂，可用于替代析氢反应 (HER) 中的商业 Pt 金属。在这项工作中，合成了 RENi 2和 RERu 0.25 Ni 1.75 (RE = Pr、Tb 和 Er)，并探索了它们的电催化 HER 活性。在未掺杂的化合物中，PrNi 2表现出最好的性能，需要55 mV的过电位，而用Ru元素部分替代Ni（PrRu 0.25 Ni 1.75）可以在10 mA/cm 2的电流密度下将过电位大大降低至20 mV. 这种增强被认为属于它们的外在特性，并且在将电催化表面积归一化后，它们的内在 HER 活性相似。单片机进一步调查2和SCRU 0.25中号1.75（M = Co和Ni）表明在该SCCO掺杂钌元件2将显著增强周围的费米能级（反键字符Ë ˚F）和削弱氢吸附能。在另一方面，对于SCNi上的反键人口2和SCRU 0.25镍1.75是类似Ë ˚F，占他们的亲密内在她的活动。

  The thermal conductivity and the electrical resistivity of polycrystalline ErNi which is ferromagnetic below 10 K have been measured as a function of temperature between 1.5 and 15 K. The Lorenz function, calculated from the measured thermal conductivity and electrical resistivity values on the same sample, exceeded the value expected for electron heat conduction. This indicates that magnons significantly

  在 10 K 以下铁磁性的多晶 ErNi 的热导率和电阻率已被测量为 1.5 至 15 K 之间温度的函数。根据对同一样品测得的热导率和电阻率值计算得出的洛伦兹函数超过了电子热传导的预期值。这表明磁振子对热传导有显着贡献。低于 3 K 的电阻率与 T 1.9 ±0.3 成正比，这是由于自旋无序电阻率。

  intermetallic compound Er 2 Ni 2 Sn (Mo 2 FeB 2 -type structure) was studied. The hydride Er 2 Ni 2 SnH 3.5 was formed under a hydrogen pressure of 65 kPa, after heating up to 373 K. The structure type of the metal sublattice was preserved, but the hydrogenation resulted in anisotropic lattice expansion prevailing in the crystallographic direction c . A lower hydride, Er 2 Ni 2 SnH 3.5- х , was obtained by heating

  摘要 研究了金属间化合物Er 2 Ni 2 Sn（Mo 2 FeB 2 型结构）的氢化。氢化物 Er 2 Ni 2 SnH 3.5 在 65 kPa 的氢压下，加热至 373 K 后形成。金属亚晶格的结构类型得以保留，但氢化导致各向异性晶格膨胀在结晶方向 c 上占优势。通过在动态真空中将 Er 2 Ni 2 SnH 3.5 加热至 573 K 获得低级氢化物 Er 2 Ni 2 SnH 3.5- х 。对于 Er 2 Ni 2 SnH 3.5-х，ab 平面中的晶格膨胀伴随着晶格参数 c 的减小。Er 2 Ni 2 Sn 是 TN = 6.1 K 的反铁磁体，而氢化物 Er 2 Ni 2 SnH 3.5 和 Er 2 Ni 2 SnH 3.5- х 保持顺磁性低至 2 K（测量极限）。

  The isothermal section of the phase diagram of the Er-Mn-Ni ternary system at 803 K was investigated by X-ray powder diffraction with the aid of microanalysis and electron probe microanalysis techniques. It consists of 14 single-phase regions, 24 two-phase regions, and 11 three-phase regions. At 803 K, the maximum solid solubility of Mn in Ni, Er2Ni17,ErNi5,Er2Ni7,ErNi3, and ErNi2 is about 31, 13, 8,4, 3, and 2 at.% Mn, respectively. The maximum solid solubility of Ni in Mn, ErMn12, and Er6Mn23 is about 3 at.% Ni, for all three compounds. The existence of ErNi4, Er4Ni17, and Er5Ni22 has not been confirmed. The existence of any ternary compound of the Er-Mn-Ni was not observed. (C) 2004 Elsevier B.V. All rights reserved.
