  Tailoring the magnetic anisotropy and domain patterns of sputtered TbFeGa alloys

  摘要：

  We report the magnetic anisotropy and domain configuration of cosputtered TbFeGa alloys. The layers were deposited from two targets with compositions TbFe2 and Fe3Ga, respectively. The structural and magnetic properties do not only depend on the composition but also on the growth conditions. Alloys with the same composition but deposited using a DC or a pulsed power source in the TbFe2 target exhibit a different magnetic anisotropy. The perpendicular magnetic anisotropy, the size and topology of domain patterns can be tailored by changing the evaporation parameters of TbFe2. The width of the stripe domain increases from 235 to 835 nm when using the DC source in the TbFe2. We correlate this effect with Tb enrichment of the TbxFe1-x phases present in the samples.

  Fe-Ga 相图：重温

  摘要：

  摘要 本文详细研究了 Ga 含量为 15-45 at.% 的 Fe-Ga 合金的显微组织和相组成，在低于 600 °C 的温度下进行长时间退火处理。本研究使用了 X 射线衍射 (XRD)、透射电子显微镜 (TEM)、振动样品磁强计 (VSM) 和电子背散射衍射 (EBSD) 结合扫描电子显微镜 (SEM) 方法。结果与 W. Koster 等人提出的四种现有 Fe-Ga 相图的预测进行了比较。(1977), J. Bras 等。(1977)、O. Kubaschewski (1982) 和 H. Okamoto (1993)。发现了几个重要的不一致，需要修正三个平衡边界的位置。低于 400 °C，一个不完整的，如果有的话，退火 300 小时后，可以看到从亚稳态（A2 或 D03）到平衡（L12）状态的转变。在 450-500 °C 下退火 300 小时的 25.5-28.1% Ga 合金仅表现出平衡

• Structural and magnetic properties of Fe3Ga alloy nanowires: Effect of post annealing treatment

  nanowires shows strong dependence on the sintering temperature. X-ray diffraction reflects the highly textured A2-disorderd phase with precipitates of DO3 and L12 phase for as-synthesized Fe3Ga NWs. As the annealing temperature increases, the intensity of strong disordered phase A2 or short range order phase DO3 suddenly decreases and grains are textured along the stable L12 phase with small precipitates

  摘要 我们报告了退火温度对直径为 80 nm 的电沉积 Fe3Ga 纳米线 (NW) 的晶体结构相变、有效各向异性能和磁化反转的影响。用于 Fe3Ga NW 元素映射的扫描透射电子显微镜 (STEM) 能量色散 X 射线 (EDX) 光谱技术清楚地显示了 Fe 和 Ga 的均匀分布。这些 NW 彼此高度对齐并具有高几何纵横比。这些纳米线的晶体结构显示出对烧结温度的强烈依赖性。X 射线衍射反映了合成的 Fe3Ga NW 的高度织构化的 A2 无序相与 DO3 和 L12 相的沉淀物。随着退火温度的升高，强无序相 A2 或短程有序相 DO3 的强度突然降低，晶粒沿稳定的 L12 相织构，并有少量 DO3 相析出。由于这些结构变化，磁化反转模式从横向模式切换为横向模式和涡旋模式的组合。室温下的角磁响应用于识别 Fe3Ga NW 的磁化反转模式。温度相关的矫顽力响应可以理解为能量势垒上的热激活，对场具有

  The standard enthalpies of formation of some shape memory alloys have been measured by high temperature direct synthesis calorimetry at 1373 K. The following results (in kJ/mol of atoms) are reported: CoCr (-0.3 +/- 2.9); CuMn (-3.7 +/- 3.2); Cu3Sn (-10.4 +/- 3.1); Fe2Tb (-5.5 +/- 2.4); Fe2Dy (-1.6 +/- 2.9); Fe17Tb2 (-2.1 +/- 3.1); Fe17Dy2 (-5.3 +/- 1.7); FePd3 (-16.0 +/- 2.7); FePt (-23.0 +/- 1.9); FePt3 (-20.7 +/- 2.3); NiMn (-24.9 +/- 2.6); TiNi (-32.7 +/- 1.0); TiPd (-60.3 +/- 2.5). The results are compared with some earlier experimental values obtained by calorimetry and by EMF technique. They are also compared with predicted values on the basis of the semi empirical model of Miedema and co-workers and with ab initio calculations when available. We will also assess the available information regarding the structures of these alloys. (C) 2011 Elsevier B.V. All rights reserved.

  The isothermal section of the Nd-Fe-Ga ternary system at 773 K was constructed using X-ray diffraction analysis. Ten binary compounds, Nd2Fe17, Nd5Fe17, Nd9Ga4, Nd5Ga3, NdGa, NdGa2, FeGa3, Fe3Ga4, alpha-Fe6Ga5 and alpha-Fe3Ga, and three ternary compounds, NdFe2Ga8, NdFe5Ga7 and Nd6Fe13Ga were existed in this isothermal section. The solid solutions Nd2Fe17.00-15.57Ga0-1.43 (Th2Zn17-type structure, space group R (3) over barm, NdFe5.46-4.65Ga6.(54-7.35) (ThMn12-type structure, space group 14/mmm) and Nd6Fe13.0-12.Ga-0(1.0-2.0) (La6Co11Ga3-type structure, space group 14/mcm) were formed by substitution of Ga for Fe in the compounds Nd2Fe17, NdFe5Ga7 and Nd6Fe13Ga at 773 K, respectively. The ternary compound NdFe2Ga8 is CaCo2Al8-type (space group Pbam) with a = 1.43742 (4), b = 1.24601 (4), c = 0.40479 (1)). The homogeneity range of NdGa2 is from 66.7 to 74.7 at.% Gain Nd-Ga side but the solid solubility of Fe in this compound is very small. The homogeneity ranges of Nd6Fe13Ga and NdFe5Ga7 are from 5.0 to 10.0 and from 50.3 to 56.5 at.% Ga, respectively. The maximum solid solubilities of Ga in Nd2Fe17 is 7.5. The homogeneity ranges for the other compounds are small. (C) 2009 Elsevier B.V. All rights reserved.

  The isothermal section (500 degrees C) of the phase diagram of the Gd-Fe-Ga ternary system was investigated by X-ray powder diffraction analysis. Eleven binary compounds, GdGa2, GdGa, Gd3Ga2, Gd5Ga3, GdFe2, GdFe3, Gd2Fe17, Fe3Ga, Fe6Ga5, Fe3Ga4 and FeGa3, have been confirmed. Two ternary compounds, GdFe5.3Ga6.7 and GdFe5Ga7, were found in this ternary system at 500 degrees C. The compound GdFe5.3Ga6.7 is orthorhombic ScFe6Ga6-type structure (space group Immm) with a = 0.8567 (9), b = 0.86960 (9) and c = 0.50782 (5) nm, while the compound GdFe5Ga7 is tetragonal ThMn12-type structure (space group 14/mmm) with a = 0.8651(1) and c = 0.50934 (6) nm. The isothermal section at 500 degrees C consists of 16 single-phase regions, 31 two-phase regions and 16 three-phase regions. The maximum solid solubilities of Ga in GdFe2, GdFe3, Gd2Fe17 are 9.2, 9.0, and 44.3 at.% respectively The homogeneity range of GdGa2 is from 22 to 33.3 at.% Ga in Gd-Ga side but the solid solubility of Fe in this compound is very small. The homogeneity range of GdFe5Ga7 is from 53.8 to 59.2 at.% Ga. Very limited solid solutions were measured in the other compounds. (c) 2008 Elsevier B.V. All rights reserved.
• Beneficial effect of boron on the structural and magnetostrictive behavior of Fe77Ga23 alloy

  Alloys of Fe77Ga23Bx (x=0, 0.025, 0.050, 0.075 and 0.1) were heat treated at 1000 degrees C/10 and characterized for microstructural features and magnetostriction. The study indicates that the parent alloy consists of three phases viz. A2 as the major phase and L1(2) and DO3 as minor phases. However, the volume fraction of L1(2) and DO3 decreases with B addition and as a result magnetostriction improves. The decrease in volume fraction of these phases is attributed to B-segregation to the grain boundary, which seems to prevent the formation of these phases. The alloy with x=0.1, however, exhibits an additional Fe2B phase and consequently its presence leads to the re-emergence of the DO3 phase, affecting the magnetostriction. (C) 2010 Elsevier B.V.
