Magnetostrictive properties of TbDyFe alloys along the direction perpendicular to the magnetic field

TbDyFe alloys play an important role in advanced actuator and sensor systems requiring either large displacement or large force, which may cause nonlinear response and performance degradation. In this investigation, experiments were performed to study the relevant magneto-mechanical response. The properties of magnetostriction along the direction perpendicular to the applied magnetic field were measured. The nonlinear behavior of the magnetostriction can be clearly explained in terms of domain rotating mechanism.
