Electrochemical deposition of FeGa∕NiFe magnetic multilayered films and nanowire arrays

Results concerning the preparation and characterization of electrochemically deposited (Fe1−xGax∕Fe1−yNiy)n (x=0.1–0.3at.%; y=0.4–0.8at.%) multilayered films and nanowires arrays are reported for the first time. The layers have been deposited successively by changing the electrodeposition potential. The combination of Fe1−xGax magnetostrictive material and Fe1−yNiy soft magnetic material shows good magnetic softness (Hc does not exceed 60Gs) and gives novel magnetostrictive behavior caused by the formation of twisted spin structures.
