1. Tailored Properties of Ferromagnetic Thin Films
Sammanfattning : Magnetic thin films and patterned nanostructures have been studied with respect to their magnetic properties using SQUID-magnetometry, magnetic force microscopy, electrical measurements, and micromagnetic calculations. Properties of vortex domain walls, trapped in Permalloy nanowires with artificial constrictions, were investigated experimentally and by numerical calculations. LÄS MER
2. Critical Phenomena and Exchange Coupling in Magnetic Heterostructures
Sammanfattning : The continuous phase transition in thin magnetic films and superlattices has been studied using the magneto-optical Kerr effect (MOKE) and polarized neutron scattering (PNR). It has been shown that the critical behavior of amorphous thin films belonging to the 2D XY universality class can be described within the same theory as crystalline sample. LÄS MER
3. Growth and Magnetic Properties of Fe- and FeNi-based Thin Films and Multilayers
Sammanfattning : This thesis concerns the growth and magnetic properties of thin films and multilayers. The samples were grown by magnetron sputtering, and characterized structurally mainly by x-ray diffraction and reflectivity. LÄS MER
4. Magnetic Ordering in Layered Magnets
Sammanfattning : The preparation of layered magnets needs the knowledge of growth techniques which are focused on the growth of Fe/V(001) superlattices. Such films have been structurally investigated by X-rays reflectivity and diffraction. LÄS MER
5. 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
