摘要：
The influence of growth conditions on the structural and magnetic properties of polycrystalline Co2FeGa Heusler alloy thin films prepared by sputtering deposition on Si substrate is investigated by XRD, VSM and Fe-57 conversion electron Mossbauer spectroscopy (CEMS). The CEMS and VSM results suggest that the films grown and annealed for a short time (1 h) at 873 K are highly ordered, with L21 structure, potentially favoring a high spin polarization. The formation of D03 ordering in the thin films is ruled out.
