Influence of size effects and granule distribution by size on optical and magneto-optical properties of nanocomposites

In this paper, the spectral dependences of transverse Kerr effect (ТКЕ) are studied experimentally and theoretically. The results obtained for deposited annealed samples with a corresponding variation in size granules. It was found that thermomagnetic annealing leads to an increase ТКЕ value magnetic nanostructures, while most noticeable changes were observed range medium high concentrations component visible region spectrum. expediency using effective approach calculating magneto-optical effects granular systems, taking into account distribution granules within lognormal granules, is shown. Based on approach, main features optical properties nanocomposites explained by example (Co45Fe45Zr10)X(Al2O3)1–X. All calculations performed Bruggemann approximation, which effectively describes nanostructures average concentrations. Size clearly manifested have significant impact nanocomposites, especially IR spectrum, associated intraband transitions. Taking particle makes it possible significantly improve description such promising inhomogeneous nanostructures. solved problem very important relevant both from fundamental point view – study magneto-optical, transport phenomena great possibilities their application modern electronics nanoelectronics. dispersion find new functional materials control wide range.
