Fe60Pt40 nanoparticles have been successfully prepared by sonochemistry method from the solution of Fe(C2H3O2)2 and H2PtCl6. The as-prepared sample then has been annealed at temperatures from 450oC to 650oC. Annealed samples have ordered L1o phase with face-centered tetragonal (fct) structure and sh...
