Abstract :
Investigation of microwave properties of 3D-nanocomposites, containing nanoparticles made of palladium and transition metals, is of fundamental interest. It is known that the length of spin diffusion is high in palladium. Electrons which cross a boundary between transition metal and palladium get a high degree of spin polarization. Resonance phenomena in 3D opal-based nanocomposites with Pd-, Fe- and Ni-containing articles are studied here through frequency and magnetic field dependences of the transmission and reflection coefficients measured in millimeter waveband. Magnetic resonance has been measured in these nanocomposites and the magnetic resonance spectra have been retrieved.
