摘要：
FePt and FePt/Ag multilayered nanowires were fabricated by a pulse-plating technique in nanoporous anodic alumina templates. The effect of Ag layers on the chemical ordering of FePt was investigated. It is found that the ordering rate of FePt is enhanced by introducing Ag layers in the FePt nanowire during post-deposition annealing. Measurements of the structure and magnetic properties of FePt 5 nm/Ag 1 nm multilayered nanowires reveal that the disorderorder transformation temperature of FePt is lowered to 350 degrees C. The possible reason for the enhancement in the ordering of FePt by introducing the Ag layers in the FePt nanowire is discussed. (C) 2010 Elsevier B.V. All rights reserved.
