  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. Magnetization dynamics in bistable systems

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Sven Backlund; [2023]
    Nyckelord :magnetism; magneto-optics; magnetization dynamics;

    Sammanfattning : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. LÄS MER

  4. 3. 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

  5. 4. 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

  7. 5. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Grunditz Jakob; [2022]
    Nyckelord :Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

    Sammanfattning : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. LÄS MER
