Abstract:
The conditions for the formation of nanocomposites based on the basis of lattice packings SiO2 nanospheres (opal matrices) with included clusters of crystalline phase of of rare-earth manganites of the general formula RMnO3 or RMn2O5, where R - Er, Gd, La, Nd, Tb, Y and Yb in interspherical nanospacing are considered. The composition and structure of the nanocomposites studied electron microscopy, X-ray diffraction and Raman spectroscopy. Results of measuring magnetic, magnetic-resonance and dielectric characteristics of the obtained nanostructures are viewed.
