1. Amorphous, Nanocrystalline, Single Crystalline: Morphology of Magnetic Thin Films and Multilayers
Sammanfattning : Properties of magnetic thin film devices cannot be understood without detailed knowledge of their structure. For this purpose, a variety of thin film and multilayer systems have been studied. LÄS MER
2. Surface Force and Friction : effects of adsorbed layers and surface topography
Sammanfattning : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. LÄS MER
3. Inhibition of Aluminium Pigments for Waterborne Coatings
Sammanfattning : Micrometer-sized aluminium flakes for use as pigments in waterborne coatings need protection, since the reaction between aluminium and water causes formation of aluminium hydroxide and hydrogen gas. The aluminium hydroxide destroys the metallic appearance of the pigment flakes and the evolution of hydrogen gas leads to a dangerous pressure build-up in the paint containers. LÄS MER
4. Magnetic Properties of Epitaxial Metal/Oxide Heterostructures
Sammanfattning : The work in this dissertation is devoted to tailoring and studying magnetic properties of epitaxial metal/oxide heterostructures. The aim is to understand the fundamental principles governing these properties and how they affect each other. The acquired knowledge can prove useful for the development of future spintronic devices. LÄS MER
5. 11B4C containing Ni/Ti neutron multilayer mirrors
Sammanfattning : The work in this thesis covers the design, growth and characterisation of neutron multilayers. The performance of these multilayers is highly dependent on the obtained interface width between the layers, even a modest improvement can offer a substantial increase in reflectivity performance.
