  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. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Viktor Olsson; [2023]
    Keywords : Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Abstract : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. READ MORE

  5. 4. Differences between solar atlases and implications on the solar oxygen abundance

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elvira Andersson; [2022]
    Keywords : oxygen abundance; 777nm triplet; solar atlas;

    Abstract : The determination of the solar oxygen abundance is a topic that has long beenunder debate, where the exact value has varied between researchers. These variationsin the oxygen abundance have implications on our understanding of the Sun and itsinterior as well as our understanding of other stars. READ MORE

  6. 5. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

    University essay from Uppsala universitet/Materialfysik

    Author : Grunditz Jakob; [2022]
    Keywords : Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

    Abstract : 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. READ MORE
