    Magneto-optical AlN/Fe/AlN structures optimized for operation in the violet spectral region

  • Original language description

    The magneto-optical (MO) polar Kerr response of AlN/Fe/AlN/Cu/Si structures was optimized for a wavelength of 410 nm. Prior to the growth of the structures, the optimal thicknesses of the individual layers were determined by modelling to find the maximumMO figure of merit. Then the structures with different thicknesses of AlN layers were grown by sputtering. The optical properties of the AlN layers, grown by reactive sputtering, were characterized by ellipsometry. The MO polar Kerr spectroscopy was employed to measure the performance of the structures in the field of 3 kOe. The MO signal was scaled for saturation (factor 7) and saturation azimuth rotation greater than 20° was observed. The agreement between calculation and experimental data was remarkable, verifying the correct set of optical and MO parameters used in the model. These results provide a guide for the design of a MO sensor with optimal performance at a desired wavelength.

    Magneto-optická štruktúra AlN/Fe/AlN optimalizovaná pre operácie vo fialovej oblasti

  • Czech description

    Magneto-optická polárna Kerrova odpoveď AlN/Fe/AlN štruktúry bola optimalizovaná na vlnovú dĺžku 410 nm. Hrúbky jednotlivých vrstiev v nanoštruktúre boli určené pomocou modelovania magnet-optickej odozvy tak, aby bolo dosiahnuté jej maximum. Pomocou naprašovania boli pripravené vzorky s meniacou sa hrúbkou AlN vrstvy. Optické vlastnosti AlN vrstvy, pripravenej reakčným naprašovaním, boli charakterizované pomocou eliprsometrických meraní. Odozva štruktúry sa merala pomocou MO polárnej Kerrovej spektroskopie v magnetickom poli 3 kOe. Magneto-optický signál bol škálovaný na saturáciu železa (faktorom 7) a bolo pozorovaná saturačná rotácia väčšia ako 20 stupňov. Významná zhoda medzi modelom a experimentálnymi dátami potvrdzuje správnu vo?bu optických a MOparametrov použitých pri modelovaní. Tieto výsledky slúžia ako vodítko pre skonštruovanie MO senzoru s optimálnym výkonom na požadovanej vlnovej dĺžke.
