  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. Exploring time-extended complexity measures in magnetic systems

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Jannes van Poppelen; [2023]
    Nyckelord :;

    Sammanfattning : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. LÄS MER

  4. 3. 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

  5. 4. Measurements and Feature Detection in Scientific Visualization

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Karl Mendoza Hallin; [2022]
    Nyckelord :;

    Sammanfattning : The work in this report focuses on atomic semi-classical magnetization dynamicsas implemented in the software package Cahmd, a classical atomisticHeisenberg-based magnetization dynamics toolbox by Danny Thonig et al. Theproject is about a state-of-the-art problem in theoretical condensed matterphysics. LÄS MER

  7. 5. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mustafa Kadhim; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.
