在0 ~ 3000 Oe的恒定磁场下，采用准静态应力-应变测量方法，研究了[110]Tb0.3Dy0.7Fe1.95合金的ΔE效应和磁弹性或磁机械振动阻尼，应力范围为0 ~-25，-50，-75 MPa。当磁场足够高（9000 Oe）时，获得线性应力-应变行为。而弹性模量E随压应力与磁场（9000 Oe）夹角θ的变化而变化，表明弹性模量E的各向异性与磁畴分布有关。
The ΔE effect and the magnetoelastic or magnetomechanical damping of vibrations in [110] oriented Tb0.3Dy0.7Fe1.95 alloy are experimentally studied by quasi-static stress–strain measurements under various constant magnetic fields between 0 and 3000 Oe, where stress ranges are taken from about 0 to -25, -50, -75 MPa. The linear stress–strain behaviour is obtained when the magnetic field is high enough (9000 Oe). However, the modulus E varies with the angle θ between the compressive stress and magnetic field (9000 Oe), which shows that the anisotropy of the modulus E is related to the magnetic domain distribution.
