Abstract  

Nanocomposites Co1-xNixFe2O4/SiO2   were prepared by sol–gel method using tetraethyl orthosilicate and nitrates, in which SiO2 is used to restrict the growth of ferrite crystalline and remove the agglomeration. XRD and TEM are used to characterize structures and morphologies. The composites sintered at 900 ℃consist of spinel phase with size ranging from 15 to 20 nm and amorphous SiO2. The doping of Ni2+ reduces the volume of unit cell of the spinel phase. The magnetic properties of the Co1-xNixFe2O4/SiO2   nanocomposites were measured by vibrating sample magnetometer and Mossbauer spectroscopy. The results indicate that the saturation magnetization decreases from 41.8 A·m2/kg to 23.0 A·m2/kg with increasing Ni2+ content. At the same time the coercivity decreases from 104.2 kA/m to 5.4 kA/m, which may originate from the variation of anisotropy induced by Co2+ ions in octahedral sites. All the samples are magnetic order state, the hyperfine magnetic field of the nanocomposites decreases with increasing Ni2+ content.
