The AE 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, -75MPa. 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.
