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. Exploring time-extended complexity measures in magnetic systems

   University essay from Uppsala universitet/Materialteori

   Author : Jannes van Poppelen; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

4. 3. Magnetization dynamics in bistable systems

   University essay from Uppsala universitet/Materialfysik

   Author : Sven Backlund; [2023]
   Keywords : magnetism; magneto-optics; magnetization dynamics;

   Abstract : 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. READ MORE

5. 4. Measurements and Feature Detection in Scientific Visualization

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Karl Mendoza Hallin; [2022]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mustafa Kadhim; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : 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.
