Effect of metal additives on L10 ordering of chemically synthesized FePt nanoparticles

The effect of additive Au, Ag, Pd, Cr, and Cu on the chemical ordering, magnetic properties, and grain growth of chemically synthesized FePt nanoparticles has been investigated. The L10 phase has been obtained by solution annealing and direct synthesis. Easy axis alignment has been obtained using dispersed L10 FePt nanoparticles.
