  TbMn2立方金属间化合物中的巨大场致体积磁致伸缩

  摘要：

  摘要 对 Laves 相化合物 TbMn 2 进行了磁致伸缩和热膨胀测量，温度范围为 5-300K，使用高达 15 T 的高脉冲磁场。在 15 T 的磁场下达到 ω=-17×10 -3 的值，这构成了稀土金属间化合物中从未观察到的最高强制磁致伸缩。这个合理的结果是基于有序 Mn 磁矩亚晶格在足够高的外加磁场下的不稳定性来解释的。

  Abstract Magnetostriction experiments have been performed on a TbMn2 polycrystalline sample. A large volume shrinkage is shown when applying a magnetic field in the ordered low temperature magnetic phase. It confirms the occurrence of a field induced first order transition from a Mn antiferromagnetism to a magnetic structure where magnetic and non-magnetic Mn are coexisting.

  Abstract Magnetostriction and thermal expansion measurements have been performed on the Laves-phase compound TbMn 2 , in the range of temperature 5–300K and using high pulsed magnetic fields up to 15 T. The forced volume magnetostriction at low temperatures within the ordered magnetic phase, reaches a value of ω=−17×10 −3 under a field of 15 T, which constitutes the highest forced magnetostriction never

  We have studied the magnetic and crystal structures of different Laves hydrides RMn2H4.5 (R = Y, Gd, Tb, Dy, Ho), having the cubic C15 structure at high temperature. We observe a strong coupling between the hydrogen and magnetic order in the frustrated Mn sublattice. The Neel temperature coincides with the ordering temperature in the hydrogen sublattice, resulting in a single magnetostructural transition. In contrast to the RMn2 compounds, in the hydrides the Mn-Mn magnetic interaction dominates and it imposes the magnetic order in the rare-earth sublattice. On the other hand, the anisotropy of the rare-earth ion strongly influences the orientation of the magnetic moments at low temperature. The Laves hydrides show a very unusual case where the structural and magnetic orders strongly interact with each other. They also offer many examples of the interplay between the localized Mn moments and the rare-earth moments. [S0163-1829(99)13213-2].
• Valence band and magnetic moment of Mn in TbMn2 and TbMn2D2 studied by Kβ5 emission X-ray spectroscopy

  Manganese K-beta 5 X-ray fluorescence spectra were measured for Mn-metal, TbMn2 and TbMn2D2. Experimental results show that in both examined Tb-Mn compounds intensities of K-beta 5 lines are greatly reduced approximately to one third of those in elemental Mn. Since the K-beta 5 line is usually believed to be due to electron quadrupole transition from Mn 3d to the 1s(-1) hole, then the observed shape of this line can probe the d-states of manganese. The results are compared to the relevant studies of K-beta 1.3 lineshape and the neutron diffraction investigations. We suggest that the manganese magnetic moment in both compounds is frustrated or in a noncollinear arrangement. (c) 2005 Elsevier B.V. All rights reserved.
