✦ Synopsis

Highly ordered (FePt) 1 À x Cu x nanowire arrays have been fabricated successfully by double-pulse electro-deposition into the pores of a porous anodic aluminum oxide template. We have found that the addition of Cu to FePt nanowires is an effective approach for reducing the ordering temperature of FePt. The coercivity of the (FePt) 88 Cu 12 nanowire arrays is around 2 kOe after annealing at 300 1C for 1 h, whereas that of FePt nanowire arrays shows several hundred Oe. X-ray diffraction characterization showed that only one set of L1 0 diffraction peaks appeared and no elemental Cu diffraction peaks were visible. This result, along with a varying c/a-lattice parameter ratio, suggests that Cu substitutes Fe or Pt in the ternary FePtCu alloy nanowires.

Ordered FePt 3 alloy nanowires have been electrodeposited into self-assembled anodic aluminum oxide templates. The radius of the FePt 3 nanowires is varied from 10 to 75 nm by controlling the synthesis conditions of the templates. Magnetization loops indicate that FePt 3 nanowire arrays that are 10
