Fe-18 at.%Ga alloys with magnetostrictive coefficients up to 400 ppm are expected to have high damping based on the magneto-mechanical hysteresis damping (MMHD) model. However, in some studies of the magnetostrictive properties of Fe-Ga alloys, it was found that the magnetization curves of Fe-Ga alloys seem to be reversible, linear, and non-hysteretic curves, which indicates the damping is zero for Fe-Ga alloys. This contradiction makes it a challenge to explore the damping mechanism of iron-based high damping alloys and possible ways to increase the damping of the alloys.
