Abstract: (1261 Views)
In this paper, the nanoparticles of FeNi3 were prepared by hydrothermal and co-precipitation methods. Also, different times and temperatures with different amounts of the hydrazine reducing hydrate were investigated in hydrothermal method. After fabrication of the samples by two methods, the samples have been characterized using the x-ray diffraction analysis (XRD), the field emission scanning electron microscopy (FESEM), and magnetic properties of the samples using a vibrating sample magnetometer (VSM). The results of diffraction pattern show that the amount of hydrazine hydrate used is very effective in single-phase sampling. FESEM images show nanoparticles, but at some temperatures and times, particles are not formed or stickiness and melting are observed. The results of VSM analysis show that the samples have high magnetic properties in both methods and not much change in saturation magnetization between samples was seen in both methods.
