The effects of Ga composition (x) on soft and high-frequency magnetic properties of 10-nm-thick B-doped Fe-Ga (Fe85.1-xGaxB14.9) thin films were investigated. A uniaxial magnetic anisotropy appeared regardless of the Ga composition. The damping constant values and magnetic inhomogeneous broadening at a zero frequency were much lower than those of the Fe-Ga polycrystalline film for all Ga compositions. These results indicate that adding B atoms to Fe-Ga thin films improves the soft and high-frequency magnetic properties of these films and suggest that Fe-Ga-B thin films are candidate magnetostrictive materials for high-frequency devices.
