- Structural Characteristics and Magnetic Properties of La doped Fe-Ga Thin Films
抄録
<p> This paper describes a study on the structural characteristics and magnetic properties of La doped Fe-Ga (Fe-Ga-La) thin films with a thickness of 50 nm. The Fe-Ga-La films showed a bcc polycrystalline structure regardless of the La content, and their crystallite size became smaller as the La content increased. Both soft magnetic properties and high-frequency magnetic properties were markedly improved in a range of La content above 4.6 at. %, which might be attributed to induced uniaxial magnetic anisotropy and magnetic inhomogeneity. In particular, the saturation magnetostriction of the films became maximum at a La content of 0.8 at. %, and its value was approximately 61.2 ppm. This result is similar to that of bulk Fe-Ga alloy with rare-earth doping. Thus, slight rare-earth doping plays an important role in the improvement of the saturation magnetostriction in Fe-Ga polycrystalline films.</p>
