Abstract:

We analyze the microwave properties of nanocomposite materials obtained by embedding opal matrices (regular packing of SiO2 spheres about 250 nm in diameter) of ferrite spinel nanoparticles in the interspherical space. It is found that the main reason for microwave changes is the magnetic resonance in a nanocomposite. In addition to the resonance, antiresonance also takes place, which is manifested as a minimum of absorbed power at frequencies higher than a certain frequency characteristic of the given type of ferrite particles. Antiresonance appears in the fields smaller than the resonance field. The amplitude of the reflected signal in antiresonance increases fourfold. The measurements are taken in the frequency range from 26 to 38 GHz. The change in the moduli of transmission and reflection coefficients in the external magnetic field in a rectangular waveguide containing a nanocomposite is analyzed. The modulus of the wave transmittance through a rectangular resonator with a nanocomposite specimen is measured. The structural analysis of nanocomposites is carried out. In addition, the magnetization curves and hysteresis loops are measured.
