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. Structural analysis of HZO thin film and electrode using X-ray diffraction

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

   Author : Elliot Winsnes; [2024]
   Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

4. 3. 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

5. 4. 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.

6. 5. Design of cooling-air permeable coil support

   University essay from KTH/Hållfasthetslära

   Author : Rozbeh Ghassemi; [2023]
   Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

   Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE
