- Abstract
Alloy (FePt)Ag ( x = 0, 6, 11, 17, 23, 27) nanoparticles have been successfully synthesized by the Sol-Gel method. The addition of Ag promoted the face-centered cubic to tetragonal phase transition, thereby reducing the temperature required for this transition comparable with pure FePt nanoparticles. Reduction of ordering temperature significantly lowers coalescence and drastically boosts the chemical ordering due to defects and lattice strain introduced by the Ag and the subsequent segregation of the Ag upon annealing. Coercivity increases with the content of Ag up to 17 %; above this percentage, the coercive field starts to decrease.
