Abstract

In this paper, we report on the synthesis of self-assembled [FePt]/sub 1-x/Au/sub x/ nanoparticles and the even greater beneficial effect of the added gold on the phase transformation. The particles were prepared using a modification of the procedure reported by Sun et.al. The synthesis involved the thermal decomposition of iron pentacarbonyl and the reduction of platinum acetylacetone and gold acetate with 1,2- hexadecanediol in phenyl ether.
