  Effect of Gd and Fe doping on magnetic properties of Al87Y5Ni8 amorphous alloy

  摘要：

  In this paper we present and discuss magnetic properties of the Al87Y5Ni8, Al87Y4Gd1Ni8, Al87Gd5Ni8, Al87Y4Gd1Ni4Fe4 and Al87Gd5Ni4Fe4 amorphous alloys. The examinations have been concentrated on a possible magnetic ordering at low temperatures and its modification by amorphous surroundings as well as different magnetic moment of alloying additions. It was shown that magnetic properties of the Al87Y5Ni8 amorphous base alloy correspond to a superparamagnetic body with Ni magnetic clusters. Magnetic moment of Ni atom in amorphous aluminum matrix is found to be 0.3 mB that corresponds to less than 50 Ni atoms per one cluster. Gd doping of the base alloy leads to a decrease of the resultant magnetic moment of Ni clusters that can be explained by some antiferromagnetic coupling Ni-Gd and Ni-Ni within magnetic clusters.

  通过杂质原子的穆斯堡尔光谱数据看到的金属间化合物的磁结构

  摘要：

  摘要 采用穆斯堡尔光谱技术研究了GdAl3 受抑反铁磁化合物中119Sn 杂质原子的磁性超精细相互作用。观察到两个强度比为 2:1 的磁子谱。在 4.5 K 时，超精细磁场的值为 4.00(2) 和 1.35(2) T。穆斯堡尔谱的特性为提出 GdAl3 晶格中自旋排列的合理模型提供了机会。在每个 GdAl3 基底层中，Gd 原子的磁矩形成三亚晶格 120° 自旋结构，这是磁受挫化合物所特有的。两个磁性非等效 Sn 位点的出现是来自位于两个相邻 GdAl3 平面中的 Gd 矩的转移极化矢量求和的结果。

  Abstract The time-differential perturbed angular correlations technique (TDPAC) has been employed for measuring the parameters of hyperfine interactions in earlier known RAl 3 compounds, synthesized at high pressure (8 GPa) and high temperature, where R = La, Ce, Sm, Gd, Tb, Dy, Ho, Er, Yb and Lu. The 111 Cd( 111 In) radioactive atom was used as a probe nucleus. The X-ray method has revealed that with

  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.

• Magnetic properties of U1−xGdxAl3 and U1−xDyxAl3 systems

  日期：1996.5

  Magnetic measurements were performed on U(1-x)R(x)Al(3) compounds with R = Gd and Dy in the temperature range 400-600 K and fields up to 7 T. UAl3 shows a spin fluctuation-type behaviour. The effective uranium moment, determined in the high temperature range, is 3.62 mu(B). When replacing U by Gd or Dy, at low temperatures, a mictomagnetic or antiferromagnetic-type ordering is evidenced. Above the magnetic transition temperatures the susceptibilities follow a Curie-Weiss-type behaviour. The effective uranium moments decrease when the rare earth content is increasing. This behaviour is attributed to gradual quenching of spin fluctuations.
• Gd_1.33Pt₃(Al,Si)₈ and Gd_0.67Pt₂(Al,Si)₅:  Two Structures Containing a Disordered Gd/Al Layer Grown in Liquid Aluminum

  Gd1.33Pt3Al8 was synthesized by the combination of Gd and Pt in excess liquid aluminum. Addition of silicon resulted in the incorporation of a small amount of this element into the material to form the isostructural Gd1.33Pt3Al7Si. Both compounds grow as rodlike crystals with hexagonal cross section. The structures were refined in the rhombohedral space group R (3) over barm, with cell parameters a = 4.3359(6) Angstrom and c = 38.702(8) Angstrom for the ternary and a = 4.3280(8) Angstrom and c = 38.62(1) Angstrom for the quaternary compound. The structure is comprised of stuffed arsenic-like PtAl2 layers and disordered Gd/Al layers. Analysis of the hk0 zone reflections indicate the presence of an a* = root3a supercell, but the structure is not ordered along c, as revealed by the highly diffuse reflections in the 0kl zone photos. Therefore, the compounds are disordered variants of the Gd4Pt9Al24 type. Magnetic susceptibility studies reveal antiferromagnetic transitions at 15 K for the ternary and 7 K for the quaternary compound. Variation of the reactant ratio produces a different structure comprised of the same structural blocks, including the disordered Gd/Al layer. Gd0.67Pt2Al5 and its quaternary analogue Gd0.67Pt2Al4Si form in the hexagonal system P6(3)/mmc with cell parameters a = 4.2907(3) Angstrom and c = 16.388(2) Angstrom for the ternary and a = 4.2485(6) Angstrom and c = 16.156(3) Angstrom for the quaternary compound.
