| Abstract: | It was investigated that the phase map of quaternion microemulsion system on AOT/n-butanol/n-heptane/water at room temperature. A FeNi3 alloy nanoparticles was prepared by simultaneous reduction of FeSO4 and NiC12 with KBH4 in the microemulsion and characterized by XRD, TEM, EDS. The analysis of TEM image shows that the average diameter of FeNi3 nanoparticals is under 25nm. The measure of mass susceptibility has indicated that the mass susceptibility is increase with intensity of magnetic field. The precursor was heat-treated under different temperature; the results suggest that the fabrication of the purity alloys depends on the annealed temperature. |
