Polymer mediated of Iron Cobalt (FeCo) Nano-particles prepared by simple sol-gel synthesis

Properties of magnetic nanoparticles compared with bulk material have been investigated because by many researchers. Iron-cobalt (FeCo) nanoparticles were synthesized by iron choloride (FeCl3.6H2O) and cobalt sulfate hexahydrate (CoSO4.7H2O) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (PVP) surfactant. The samples were characterized to identify the physical properties. XRD pattern of FeCo samples showed the structure of body center cubic (bcc) structure. The particle size of as-prepared sample was around 20 nm and annealed samples were around 30 in diameter at 500 oC. The TEM studies show that the particles changed to sphere-liked shaped particles by increasing annealing temperature. The sharp peaks in FTIR spectrum determined the element of Fe-Co nanoparticles.
