  一些轻稀土-铝拉夫相化合物中的磁致伸缩应变

  摘要：

  摘要 一些 RAl 2 (R = Pr、Nd 和 Sm) 化合物的磁致伸缩测量是在 4.2 K 至高于其磁有序温度 ( T c ) 和高达 2.1 T 的外加场中进行的。PrAl 2 表现出巨大的磁致伸缩（ ≈10 -3 ) 和明确定义的饱和度低于 30 K 和约 0.8 T。对于 SmAl 2 没有观察到饱和度达到最高可用的外加场。这意味着该材料是高度各向异性的。NdAl 2 的应变在更高的场中表现出变化是符号。发现PrAl 2 的应变随温度的变化与单离子磁致弹性理论非常一致。对于所研究的化合物，观察到大体积应变。这些应变归因于晶体场相互作用的体积依赖性。

  Abstract The enthalpy of solution of Eu in Al and the standard molar enthalpy of formation of LnAl 2 (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) were determined by dissolution calorimetry, using a calorimeter based on liquid aluminium. Experimental results are compared with model predictions.

  We have measured the 3d and 4d core-level X-ray photoelectron spectra of rare earths in RERuSn3 (RE = La, Ce, Pr, Nd and Sm) and related rare-earth compounds. The Ce 3d spectra of CeRuSn(x) (x= 2.85, 3.0 and 3.15) show the common features observed in other cerium compounds. In the spectra, f0 structures cannot be apparently distinguished from other prominent structures f1 and f2 peaks, and broad structures are observed at the high binding energy side of the f1 peak. For SmRuSn3, both Sm 3d and 4d spectra show strong Sm'' components and the Sm valency is estimated to be 2.95 +/- 0.02.

• Raman scattering in the intermetallic compounds Sm1−xGdxAl2 (x=0, 0.01 and 0.02)
  作者：Jinrui Su、Changfei Zhu

  DOI：10.1016/j.materresbull.2003.06.001

  日期：2003.12

  Raman spectra of polycrystalline intermetallic compounds Sm1-xGdxAl2 (x = 0, 0.01 and 0.02) have been obtained over the temperature range 83-293 K. Raman lines at similar to115 cm(-1) were observed in each of the samples at room temperature. These Raman lines were associated with the optical modes of phonons. The Raman line splits into two lines at low temperature. It is suggested that the splitting at low temperature is related to the interaction between magnetic excitations and phonons.
