Abstract：It is have been developed that effect of correlative parameters on Nanoparticles Gelatin Nickel Iron composite particles have been prepared with the microemulsion chemical tailoring method.The results of by XRD.TEM and EDS show that the ultrafine particles have been a spheroid coated by Gelatin.Their average sizes are 48～136nm, and particles sizes are 2.3～3.4nm,about 21～40 Nickel Iron particles on per spheroid.It is also shown that in which NiFe 2O 4 and FeNi 3 were formed by analysis of XRD and EDS.

Key words：microemulsion; chemical tailoring; composite Ni/Fe; nanoparticles
