Abstract

Microwave properties of magnetic photonic crystals, namely, silica opal matrices with embedded nickel-zinc iron spinel nanoparticles have been investigated in the frequency range from 26 to 38 GHz. The experiments were carried out using electromagnetic wave penetration through a sample placed into a waveguide and reflection of the wave. It has been found that these magnetic nanocomposites show giant “antiresonance”-type and resonance-type dependences of the reflection coefficient versus magnetic field. Magnetic resonance and “antiresonance” spectra have been studied. Variation of the reflection coefficient under “antiresonance” condition exceeds 150% that enables to use that material in magnetic field driven devices of millimeter waveband.
