Simulation of magneto-optical properties of nanocomposites (CoFeZr)x(Al2O3)1-x

Abstract

Abstract The magnetooptical spectra of the transverse Kerr effect of (CoFeZr)x(Al2O3)1-x nanocomposites are calculated within the framework of the symmetrized Maxwell-Garnett (SMG) approximation. The quasi-classical size effect and the size distribution of the granules were taken into account. The calculation results for the spectral range 0.5-3.5 eV and different concentrations of the magnetic component are in semi-quantitative agreement with the experimental data. A possible reason for the existing discrepancy is the difference between the optical and magneto-optical parameters of ferromagnetic granules from those corresponding for bulk samples.
