  1. 6. Calibration of XRF composition measurements with RBS, on BaZrS3 thin films

    L3-uppsats, Uppsala universitet/Materialfysik

    Författare :David Sörme; [2023]
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  3. 7. 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. 8. 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. 9. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Ali Rostom; David Holmgren; [2022]
    Nyckelord :Fe MgO superlatice; interlayer exchange coupling; Van der Pauw; electronic transport; magnetic field; resistive properties; 3D memory storage;

    Sammanfattning : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. LÄS MER

  7. 10. 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
