Abstract. Opal matrixes represent the regular 3D-pack of spherical
particles of amorphous SiO2, forming an ordered system of voids.
Opal matrixes with spherical particles of SiO2 diameter d ≈ 260 nm (Δd ≈ 2%) were synthesized. Nanocomposites
were formed by filling voids (occupying ~26% of the volume) of opal matrixes by salt solutions, low-temperature
heat treatment at 625–825 K and annealing at 975–1475 K. The formation in the voids of opal
matrixes, depending on synthesis conditions, of the synthesized substances, SiO2
and products of interaction synthesized substances with SiO2 are
submitted. The frequency dependences of the conductivity, real and imaginary
components of the dielectric and magnetic permeability of nanocomposites
containing crystallites 16–65 nm in size of magnetic materials — double phosphates (LiNiPO4,
LiCoPO4) and vanadates (GdVO4 and DyVO4) were
measured. The dielectric losses of nanocomposites remain low (at a level of
~0.06) in the frequency range 107–1010 Hz for nanocomposites with
DyVO4 and LiCoPO4. The dielectric loss increases both in
the direction of low frequencies (<106 Hz) and in the direction of THz
frequencies. Investigations have demonstrated that the measured parameters are
influenced by the phase composition, as well as the structural and magnetic
state of the synthesized substances.
Keywords: opal matrixes; nanocomposites; double phosphates of Li and Ni(Co);
vanadates of Gd and Dy; dielectric and magnetic properties.
