Abstract
The axial and transversal linear magnetostrictions (λ∥ and λ⊥) in [1 1 0] oriented polycrystalline Tb0.3Dy0.7Fe1.95 alloys were measured simultaneously under uniaxial magnetomechanical loading to get the forced volume magnetostriction (ω=λ∥+2λ⊥). Despite the almost zero ω observed in Terfenol-D single crystals, it reaches up to 1000×10-6 in polycrystalline Tb0.3Dy0.7Fe1.95 alloys near the saturation magnetic field under a stress above 50 MPa.
