  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    University essay from Uppsala universitet/Materialteori

    Author : Viktor Frilén; [2023]
    Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Abstract : 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. Reducing Power Losses by Optimizing Cooling in Final Annealing of Non-Oriented Electrical Steel

    University essay from KTH/Materialvetenskap

    Author : Emil Rosqvist; [2023]
    Keywords : ;

    Abstract : Surahammars Bruks AB produces non-oriented electrical steel used in several types of motors and generators. Because of recent years exponentially growing market for electrical vehicles, non-oriented electrical steel used in electrical vehicle motors is becoming an increasingly important product. READ MORE

  4. 3. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  5. 4. Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Cornelia Säll; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. READ MORE

  6. 5. Semiconducting TiO2 for High Performance Ferroelectric Tunnel Junctions

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Erik Wikare; [2022]
    Keywords : Technology and Engineering;

    Abstract : The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. READ MORE
