Structural, magnetic, and magnetostrictive properties of Laves (Tb0.3Dy0.7)1−xPrxFe1.55 (0≤x≤0.4) alloys

Enhanced magnetoelastic effect in Laves (Tb,Dy)Fe2 alloys with the joint introduction of Pr and Nd

“…This property can be comparable with the recently developed Pr/Ndcontaining anisotropy compensation Tb 0.1 (Pr 0.5 Nd 0.5 ) 0.9 Fe 1.93 compound, k a about 600 ppm at 2 kOe [14]. At the relatively high field of 10 kOe, k a of x = 0.03 is slightly less than that of x = 0, which may be attributed to the competition between the spontaneous magnetostriction coefficient k 111 (k 100 ) and the magnetic anisotropy [15]. To better understand the impact of magnetocrystalline anisotropy variation on the magnetostriction, the magnetic-field dependence of the normalized magnetostriction k a /k 0S is plotted in Fig.…”

Research on a novel force sensor based on giant magnetostrictive material and its model

“…The emergence of giant magnetostrictive material (GMM) provides a new type of sensitive material for the development of magnetostrictive force sensor. By right of its excellent characteristics of large magnetostrictive coefficient at room temperature (1500 × 10 −6 -2000 × 10 −6 ) which is 100-1000 times higher than that of common magnetostrictive material [6], low magnetocrystalline anisotropy, high magnetomechanical coupling coefficient, fast response speed, etc., GMM attracts wide attention at home and in abroad academic circles, and industrial community [7].…”

Magnetomechanical properties of epoxy-bonded Sm1−xNdxFe1.55 (0≤x≤0.56) pseudo-1–3 magnetostrictive particulate composites

“…Accordingly, several good candidates have been prepared by substituting Pr or Nd for Tb and/or Dy in Terfenol-D. These include: (Tb 0.3 Dy 0.7 ) 1−x Pr x Fe 1.55 (0 ≤ x ≤ 0.4) [11], Tb 0.2 Dy 0.8−x Pr x (Fe 0.9 B 0.1 ) 1.93 (0 ≤ x ≤ 0.4) [12], Tb x Nd 1−x Fe 1.9 (0 ≤ x ≤ 0.8) [13], etc. For the equally important negative magnetostrictive alloy systems, reports are relatively limited.…”
