  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Viktor Frilén; [2023]
    Nyckelord :moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Sammanfattning : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  3. 2. Development of MOKE spectrometer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Sebastian Åberg; [2023]
    Nyckelord :MOKE; Spectroscopy;

    Sammanfattning : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. LÄS MER

  4. 3. Preparation and Characterization of Tb-Co Magnetic Films

    L2-uppsats, Uppsala universitet/Materialfysik

    Författare :Roméo Beignon; [2022]
    Nyckelord :Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

    Sammanfattning : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. LÄS MER

  5. 4. Theoretical and experimental investigation of themagneto-optical eect in graphene in the THz region

    L1-uppsats, Uppsala universitet/FREIA

    Författare :Mircea-George Coman; [2022]
    Nyckelord :;

    Sammanfattning : In many optics applications we need lenses with dynamically tunable focal lengths. One design of such a lensis developed in and it relies on the magneto-optical eect. In this design, a graphene layer is placed ina magnetic eld that varies quadratically in space. LÄS MER

  7. 5. Investigation of Inverse Magnetostriction inCobalt Films and Nanowires

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Ahmad Montaser Lababidi; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis, a study of the inverse magnetostriction (the Villari effect) of Co nanowires and films is presented. The main objective was to investigate the stability of the Co nanowires’ magnetic properties, i.e. LÄS MER
