  1. 1. 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

  2. 2. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Peter Dagbui; [2023]
    Nyckelord :Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Sammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER

  3. 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

  4. 4. The Magnetic Properties and Fabrics of Upper Pleistocene Loess on La Motte, Jersey, and their Palaeoclimate Implications

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anya Hawkins; [2022]
    Nyckelord :last glacial; magnetic susceptibility; AMS; temperature dependent magnetic susceptibility; palaeowind reconstruction;

    Sammanfattning : The island of Jersey is an interesting location for palaeoclimate reconstruction given the likely impact of variations in North Atlantic climate and European ice sheet extent during the last glacial period considering their proximal location. These last glacial climatic variations are recorded in the loess sequence from La Motte, Jersey and in order to reconstruct these changes, a detailed magnetic analysis was performed. LÄS MER

  5. 5. Computational Study of the Magnetocrystalline Anisotropy Energy of Ordered CoPt

    L1-uppsats, Uppsala universitet/Materialteori

    Författare :Max Fusté Costa; [2022]
    Nyckelord :;

    Sammanfattning : The study of the properties of magnetic materials is of primary importance in the development of newtechnologies. In this project, we aim to investigate the symmetries of some of the relevant properties ofa cobalt and platinum alloy that emerge from the symmetry of the crystal structure of the alloy. LÄS MER
