Abstract

Equiaxed FeCo particles with mean diameter of 12 nm were prepared by reducing a mixture of iron chloride and cobalt chloride with NaBH₄ in the isooctane/AOT/ H₂O reverse micelle system. It was found that the extent of oxidation of the product, and hence its properties, were sensitive to the purging of liquid reagents by nitrogen as well as the annealing conditions. X-Ray Diffractipn (XRD) results showed that the assynthesized particles formed a complex compound that later leads to formation of FeCo. Transmission Electron Microscope (TEM) showed that the particles were monodispersed with average size of 12 nm. Upon annealing, crystallization takes place and magnetic properties were greatly enhanced. Vibrating Sample Magnetometer (VSM) results showed that the material exhibited a saturation magnetization of 110 emu/g.
