Three-dimensional nanocomposite metal dielectric materials on the basis of opal matrices

The microwave properties of 3D nanocomposites based on opal matrices containing one or two transition metal particles have been investigated. Phase analysis of the nanocomposites has been carried out. Magnetic field dependences of transmission and reflection coefficients were obtained. Magnetic resonance and antiresonance spectra have been reconstructed. Frequency dependences of resonance and antiresonance amplitude have been obtained. It has been found that the magnetic resonance amplitude of a nanocomposite containing particles of two metals is essentially higher than that of a nanocomposite with particles of one metal. © 2013 Pleiades Publishing, Ltd.The work was financially supported in part by the Russian Academy of Sciences in the framework of the “Basic Research in Nanotechnologies and Nano-materials” Program (project no.
