This paper describes static and high frequency magnetic properties of Fe100-xGax polycrystalline films (x = 18.5, 24.9, and 33.4) with various thickness between 5-100 nm. The saturation magnetostriction (λs) for each x become lower than those of Fe-Ga single crystal films and Fe-Ga bulk alloy regardless of the film thickness, which may be attributed to the crystalline orientation in these films. On the other hand, for every x, the relationship between the in-plane effective damping constant (α//) and the film thickness is almost same. Their values become higher than those of other Fe-binary alloy thin film with soft magnetic properties, which may be attributed to the coexistence of both intrinsic and extrinsic damping. These results suggest that the reduction of α// is one of the most important for the high-frequency device applications of Fe100-xGax polycrystalline films with various film thickness.
