摘要：
Analysis of the X-ray absorption near-edge structure of (Co45 Fe45Zr10)x(SiO2)1-x nanocomposites has shown the presence of interaction between atoms of the metallic and dielectric components in the nanocomposite. In this process, d-metal ions (Fe3+, Fe2+, Co2+) play the most active role. They interact with oxygen ions of the dielectric component and form not only Fe2 O3 × CoO nanoferrites but also silicates of d metals. © Allerton Press, Inc. 2008.
