Magnetic Properties Model of Fe-Ga alloy

The magnetostriction and magnetization of Fe-Ga alloy (Galfenol) rods were modeled according to the free energy theory, the JA model and the SW model, taking into account anisotropy effect and loss effect. The magnetostriction of Galfenol rods and the magnetization of Galfenol rods at different frequencies and stresses were calculated based on the constitutive models. The calculating results are consistent with experimental ones. The model can calculate the magnetostriction properties and magnetic properties of magnetostrictive materials at different excitation frequencies and stresses.
