  通过磁化和磁阻等温线揭示流动的 Fe3Ga4 的弱停滞和场驱动的一级磁相变

  摘要：

  摘要 报道了络合物3 d 电子基Fe 3 Ga 4 的详细磁学研究。它分别在 380 和 70 K 左右经历顺磁到反铁磁 (TN) 和反铁磁到铁磁 (TC) 的转变。场冷却 (FCC) 和场冷却变暖 (FCW) 的热滞后暗示居里以下的一阶相变温度。通过探索类似逮捕的一阶现象，建议铁磁相和反铁磁相的弱相共存。在中间温度范围内，证实了从反铁磁相到铁磁相的场驱动变磁转变。进一步使系统非常接近 TN ，场引起的跃迁消失并且在 TN 之上主要顺磁贡献是明显的。

  cuboctahedra of the Au3Cu type. Er4Fe0.67Ga12 is iron-deficient, leading to a distortion of the octahedral and cuboctahedral environments due to the splitting of the Ga2 site into Ga2 and Ga3 sites. Further, interstitial octahedral sites that are unoccupied in Ln4FeGa12 (Ln = Y, Tb, Dy, and Ho) are partially occupied by Fe2. Y4FeGa12 exhibits weak itinerant ferromagnetism below 36 K. In contrast, Tb4FeGa12

  Metallic Fe3Ga4 displays a complex magnetic phase diagram that supports an intermediate antiferromagnetic (AFM) helical spin structure (HSS) state at room temperature which lies between two ferromagnetic (FM) phases. Magnetic measurements along the three crystallographic axes were performed in order to develop a model for the temperature and field dependence of the HSS state. These results show that

  studied to investigate changes in crystallographic and magnetic properties induced by annealing. Results show a significant trend in the evolution of the (incommensurate spin density wave) ISDW-FM (ferromagnetic) transition temperature as a function of the refined unit cell volume in annealed samples. Strikingly, this trend allowed for the tuning of the transition temperature down to room-temperature

  已经研究了合成后退火温度对 Fe 3 Ga 4电弧熔化样品的影响，以研究退火引起的晶体学和磁学性质的变化。结果显示，作为退火样品中细化晶胞体积的函数，（不公度自旋密度波）ISDW-FM（铁磁）转变温度的演变趋势显着。引人注目的是，这种趋势允许将转变温度调整到室温 (300 K)，同时保持温度的急剧转变，为使用 Fe 3 Ga 4敞开了大门在功能设备中。通过高分辨率 X 射线衍射数据的 Rietveld 精修进行的晶体学分析表明，无论退火温度如何，电弧熔化的化学计量 Fe 3 Ga 4都是多相的，具有少量的 FeGa 3在较高的退火温度下相分数降低。为了验证 ISDW-FM 转变温度相对于晶胞体积的趋势，进行了高压磁力测定。这表明 FM-ISDW (~ 68 K) 和 ISDW-FM (~ 360 K) 转变温度可以分别随外部压力线性调整、增加和减少。因此，外部压力和随之而来的晶体学变化使 ISDW

  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.
