چکیده انگلیسی
Fe100âxCox (x = 25 â 45) nanoparticles have been successfully prepared from FeCl2 and Co(C2H3O2)2 by thermal decomposition process in solution of polyethylene glycol and NaOH (polyol method). The influence of pH level and Co concentration on structure and magnetic properties of the Fe-Co nanoparticles were investigated. The X-Ray Diffraction (XRD) results confirm the formation of a body centered cubic single phase of the Fe(Co) nanoparticles. The Scanning Electron Microscopy (SEM) images show the grain size of the samples is about 60Â nm. Saturation magnetization the Fe-Co nanoparticles strongly depends on the Co concentration and pH level in the fabrication process. The optimal pH level and Co concentration for the Fe-Co nanoparticles were found to be 7 and 35Â at%, respectively. A quite high saturation magnetization of 228Â emu/g has been achieved for the Fe-Co nanoparticles.
