  1. 1. 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

  3. 2. 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. 3. 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

  5. 4. Fabrication and characterization of novel nano-magnets

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Louise Lifvenborg; [2020]
    Nyckelord :nanotechnology; nano-magnets; magnetism; Master s Programme in Materials Engineering; Q; lithography;

    Sammanfattning : Magnetic data storing has been of great interest since 1950 when the first magnetic hard drive was fabricated. A lot has happened since then, but there is still a need for smaller and cheaper devices.  One way to achieve this is by creating nano-sized ferromagnetic areas in a thin film at room temperature, or nano-magnets.

  7. 5. Tailoring the magnetic anisotropy in amorphous FeZr-based thin films on flexible and solid substrates

    Master-uppsats,

    Författare :Matteo Menniti; [2018]
    Nyckelord :amorphous; magnetic; materials; anisotropy; material characterization; iron; cobalt; zirconium; boron; moke; magneto optical; tailoring; material design; flexible; magnetostriction; functional materials; sensor;

    Sammanfattning : In this thesis the magnetic properties of novel amorphous magnetic materials grown on a flexible substrate of polyethylene naphthalate and a silicon wafer have been analyzed and characterized. The analyzed films are two films of amorphous Cobalt-Iron-Zirconium(Co36Fe53Zr11 & Co37Fe55Zr8) grown on the flexible substrate and two films of amorphous (Fe89Zr11) doped with boron (B). LÄS MER
