Formation of nanocomposites based on the lattice packing of SiO2 nanospheres (opal matrices) with clusters of metals (Ni, Fe) embedded into nanopores between spheres. For the formation of nanocomposites used samples opal matrices with dimensions of single-domain regions > 0,1 mm3, diameter SiO2 nanospheres was ~ 260 nm. Obtained nanocomposites volume > 1 cm3 in filling > 20 % of interspherical nanospacing crystalline compounds of nickel and iron. The composition and structure of the nanocomposites was studied by electron microscopy, X-ray diffraction and Raman spectroscopy. The dependence of the composition of synthesized materials on the conditions of their preparation are submitted. Results of measurements of the frequency (ranging 10-3-1012 Hz) dependences of magnetic and dielectric characteristics of the obtained nanostructures are presented.
