Results concerning the preparation and magnetic characterization of electrochemically deposited [Fe80 Ga20 /Co75 Fe10 B15 ]n multilayered films and nanowire arrays are reported for the first time. The deposition bath consisted in a single mixed solution of FeSO4middot7H2O, Ga2(SO4)3middotH2O, CoSO4middot7H2O, C2H 10BN, and H3BO3. The layers have been deposited successively by changing the electrodeposition potential. The composition and thickness of the different layers were tailored through optimizing deposition parameters such as buffer additives and applied voltage. Two hundred sequences multilayered nanowires were electrodeposited into commercially available nanoporous alumina membranes with pore diameters of 100 nm and lengths of 50 mum. Multilayered films 4-5 mu m thick have been obtained by electrodepositing 50 consecutive sequences of FeGa and CoFeB. The multilayered structures consisting FeGa magnetostrictive alloy and CoFeB amorphous magnetic material are magnetically soft (Hc does not exceed 1.6 kA/m).
