FeGa/FeNi　bilayer　structures　with　different　deposition　order　were　fabricated　by　the　electrodeposition　method　on　indium　tin　oxide　(ITO)　substrates.　The　structure,　morphology,　static　and　dynamic　magnetic　properties　of　FeGa/FeNi　(FeNi/FeGa)　films　were　investigated.　The　bilayer　structures　exhibit　extremely　various　magnetic　properties　with　different　deposition　order　which　could　be　attributed　to　the　different　coupling　interaction　in　the　interface.　When　FeGa　is　on　top,　the　bilayer　structures　show　lower　coercivity　than　when　FeNi　is　on　top.　Meanwhile,　increase　of　the　proportion　of　FeNi　in　the　bilayer　structure　could　affect　the　H-c　and　M-r/M-s.　The　ferromagnetic　resonance　peak　of　FeGa　on　top　moves　to　a　high　field　compared　with　FeNi　on　top.　Moreover,　FeGa　on　top　shows　improved　complex　permeability　and　a　clear　resonant　phenomenon　of　the　magnetization.　These　properties　make　FeGa/FeNi　bilayer　structure　a　potential　candidate　for　high-frequency　application.
