  超磁致伸缩 PrxTb1−xFe1.9 合金的高压合成

  摘要：

  PrxTb1−xFe1.9 (0⩽x⩽1) 具有立方 Laves 相的磁致伸缩合金已通过高压合成方法合成。研究了 PrxTb1−xFe1.9 (0⩽x⩽1) 合金的晶体结构、磁性、磁晶各向异性和磁致伸缩。Pr0.9Tb0.1Fe1.9合金实现了成分各向异性补偿，在室温13kOe下表现出低磁晶各向异性和大磁致伸缩值（λ‖−λ⊥=1497ppm）。这些特征表明 Pr0.9Tb0.1Fe1.9 合金可能是磁致伸缩应用的有希望的候选者。

  formation of non-stoichiometric TbFe2Mnx compounds results from partial substitution of Tb by Mn in (6c) positions. It was found a characteristic value for the cubic MgCu2-type lattice parameter ac ≈ 7.2 Å. If binary RT2 (R is a rare-earth metal, T – 3d transitional metal) compounds have lattice parameter smaller than 7.2 Å, we can expect large values of Mn concentration (x > 0.4) in non-stoichiometric RT2Mnx

  Tb75Fe25 nanoglass samples were prepared by cold pressing amorphous nanoparticles (produced by the inert gas condensation method). One of the bulk nanoglass samples was severely plastically deformed using high-pressure torsion. The structure of the deformed and non-deformed nanoglass samples was examined by X-ray diffraction. Differential scanning calorimetry of the samples showed a higher thermal stability of the non-deformed sample when compared to the severely plastically deformed sample. The results suggest a more relaxed structure being present in the non-deformed sample as compared to that of the deformed sample. Transmission electron microscopy performed on the deformed sample revealed the presence of shear band-like features with indications of crystalline terbium precipitates. Atom probe tomography was used to identify compositional changes in both the non-deformed and the deformed samples. The non-deformed structure showed a homogeneous distribution of both Tb and Fe, whereas a terbium enhancement (up to 90%) was observed within the shear bands of the deformed sample. The Tb segregation and crystallization within the shear bands observed both by electron microscopy and atom probe tomography are clear indications of the structural changes occurring in the shear band regions during the deformation. It is concluded that the diffusion is enhanced leading to the compositional variation within the shear bands. (C) 2019 Elsevier B.V. All rights reserved.
• Study on the magnetic properties and phase composition of Tb1−xPrxFe1.96 () compounds

  The magnetic properties and the phase structure of Tb1-xPrxFe1.96 (x = 0-0.7) were studied. It is found that the saturation magnetization on easy axis is decreased with increasing of Pr content, from 77.24 Am-2 kg(-1) for x = 0, reduces to minimum value of 11.84 Am-2 kg(-1) for x = 0.5, and returns to 37.14 Am-2 kg(-1) for x = 0.7. The non-cubic phases appear beyond x = 0.2 and the matrix changes from TbFe2 phase for x = 0 to (Tb, Pr)Fe-3 phase for x = 0.4, at last to (Tb, Pr)(2)Fe-17 phase for x = 0.7. The compound structures turn more complex as the Pr content increased. (c) 2005 Elsevier B.V. All rights reserved.

  Fe-57 Mossbauer spectra in amorphous TbxFe1-x films (AF) and Tb/Fe multilayers (MLs) were measured for a wide range of concentration and layer thicknesses. A small angle between the film normal and direction of H-bf was observed. This effect and the concentration dependence of Fe-57 hyperfine field in amorphous TbFe films are discussed.
