  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Emelie Zhu; [2024]
    Keywords : Physics and Astronomy; Technology and Engineering;

    Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

  3. 2. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE

  4. 3. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    University essay from KTH/Materialvetenskap

    Author : Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Keywords : ;

    Abstract : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. READ MORE

  5. 4. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Peter Dagbui; [2023]
    Keywords : Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Abstract : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. READ MORE

  6. 5. 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
