1. Hydrogen in ultrathin vanadium layers
Sammanfattning : The influence of elastic boundary conditions on the thermodynamics of hydrogen in vanadium were investigated using resistometry, x-ray diffraction and nuclear reaction analysis. To provide varying lattice strain states Mo/V (110) and Fe/V (001) superlattices with thickness L of individual layers in the range 3-16 monolayers (ML) were used. LÄS MER
2. Characterization of HPV-induced vaginal and vulvar carcinoma
Sammanfattning : .... LÄS MER
3. 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
4. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices
Sammanfattning : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. LÄS MER
5. 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
