1. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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.

2. Probing magnetic Dynamics inNanoarrays using AC susceptibility
University essay from Uppsala universitet/MaterialfysikAbstract : This project revised a magneto-optical ac susceptometer aiming to improve the experimentalapproach to investigate the magnetization dynamics of magnetic nano arrays.First the experimental setp was equipped with a new Helmholtzcoil which enables strongerAC magnetic eld compared to the installed coils on the system. That includes i.e. READ MORE

3. Effective Visualization of Magnetization Dynamics.
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Simulations on magnetization dynamics are of great interest on current research. Unlike computational fluid dynamics, magnetization dynamics has not received much attention from the visualization community. READ MORE

4. Micromagnetic simulations of magnetization dynamics in iron-palladium nanostructure arrays
University essay from Uppsala universitet/MaterialfysikAbstract : Previous investigations of FePd circular island arrays have shown the hysteresis-free switching from vortex to collinear magnetic state at high temperatures [1]. This raises interest in the exploration of the temperature and inter-island interaction effect on the magnetization dynamics in this kind of structures. READ MORE

5. Element-Specific Magnetization Dynamics Using T-MOKE at the HELIOS Laboratory
University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysikAbstract : Magnetism is a familiar phenomenon, and is applied in a variety of devices, from simple ones, like compasses, to the more sophisticated magnetic hard disk drives. It is also known that the magnetization of a material can change, for example by heating or by exposure to an external magnetic field. READ MORE
