Abstract

CoPt and FePt nanowire arrays were successfully prepared by electrodeposition into nanochannels of porous alumina membranes. The as-deposited CoPt alloy has a face centred cubic structure and displays soft magnetic properties. Heat treatment at 700 °C for different durations, under vacuum condition was carried out in order to obtain the ordered face centred tetragonal phase L1₀, exhibiting hard magnetic properties. After annealing, arrays of nanowires actually show hard magnetic properties with coercive fields up to 1.1 T at room temperature. Phase transformation, structural and magnetic properties were analysed and necessary conditions to obtain optimum magnetic properties are concluded. The first results obtained with FePt nanowires denote a more complicated system since the as-deposited material shows no magnetization. Magnetism appears only after annealing at 700 °C minimum. Coercivity up to 1.1 T has been obtained at room temperature but with inhomogeneous phase composition.

<fC01 i1="01" l="ENG"><s0>CoPt and FePt nanowire arrays were successfully prepared by electrodeposition into nanochannels of porous alumina membranes. The as-deposited CoPt alloy has a face centred cubic structure and displays soft magnetic properties. Heat treatment at 700 °C for different durations, under vacuum condition was carried out in order to obtain the ordered face centred tetragonal phase L1<sub>0</sub>
, exhibiting hard magnetic properties. After annealing, arrays of nanowires actually show hard magnetic properties with coercive fields up to 1.1 T at room temperature. Phase transformation, structural and magnetic properties were analysed and necessary conditions to obtain optimum magnetic properties are concluded. The first results obtained with FePt nanowires denote a more complicated system since the as-deposited material shows no magnetization. Magnetism appears only after annealing at 700 °C minimum. Coercivity up to 1.1 T has been obtained at room temperature but with inhomogeneous phase composition.</s0>
