N2 - The preparation of Fe100-xNix-SiO2 (x = 0, 20, 60, 80) granular solid using a sol-gel method is investigated by means of X-ray diffraction and electron transmission micrography. Pure Fe metal, Fe40Ni60 and Fe20Ni80 ultrafine alloy particles dispersed in Fe-SiO2, Fe40Ni60-SiO2 and Fe20Ni80-SiO2 granular solid have been fabricated which are confirmed by the result of the XRD and the Mössbauer spectrums. The evolution of the magnetic properties for the Fe40Ni60-SiO2 and Fe20Ni80-SiO2 granular solid during reducing are described in detail and explained by using superparamagnetism, single-domain and multidomain theory.
