1. Magnetization dynamics in bistable systems
Kandidat-uppsats, Uppsala universitet/MaterialfysikSammanfattning : 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. LÄS MER
2. Additively Manufactured Rare Earth Free Permanent Magnets
Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Oorganisk kemiSammanfattning : It’s well known that MnAl(C) material consists of a metastable phase (τ) with promising ferromagnetic properties, produced either by controlled cooling from the high-temperature hexagonal ε-phase or rapid cooling that freezes the ε-phase followed by low-temperature annealing. Due to the high cooling rates involved, additive manufacturing (AM) especially selective laser melting (SLM), has been identified as a possible method to retain the high-temperature ε-phase, hence containing a potential capacity to produce permanent magnets upon low-temperature annealing.

3. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project
Master-uppsats, Uppsala universitet/GeofysikSammanfattning : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. LÄS MER
4. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices
Kandidat-uppsats, Uppsala universitet/MaterialfysikSammanfattning : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. LÄS MER
5. Quantum Landau-Lifshitz-Gilbert Dynamics of a Dimer
Master-uppsats, Uppsala universitet/Teoretisk fysik; Uppsala universitet/MaterialteoriSammanfattning : The classical Landau-Lifshitz-Gilbert (LLG) equations are of crucialimportance in micro-magnetism, but a true quantum-mechanical descriptionwas not found until 2013. However, very few realistic quantumsystems have been modeled using it. LÄS MER
