FACILE SYNTHESIS OF FECO NANOPARTICLES BY ONE-POT POLYOL PROCESS

Abstract

Ferromagnetic FeCo nanoparticles were prepared by a simple one-pot polyol process and followed by simple annealing treatment. The prepared ferromagnetic FeCo nanoparticles have spherical shape and the size was controlled by the annealing temperature. Importantly, single FeCo phase was obtained at 400°C and these samples have spherical shape and size about 50 nm. While at higher temperature (at 600°C) the nanoparticles have very lower aggregation and have higher coercivity. The prepared FeCo  nanoparticle at low temperature with good magnetic properties are to be considered as potential candidate for many applications.
