6. Magnetism in layered materials
Abstract : Magnetic properties of layered materials have been studied by means of electronic structure calculations based on density functional theory.The occurrence of confined quantum-well states in thin films has been investigated and put into relation with the topology of the corresponding bulk Fermi surface.

7. Magnetoplasmonic nanostructures
Abstract : Surfaces that are nanopatterned, metallic, and magnetic can support surface plasmon resonances, providing an alternative and effective way to reconfigure flat optical components. Utilising a range of near- and far-field characterisation techniques, the optical and magneto-optical properties of lithographically patterned thin magnetic films are investigated. READ MORE

8. Ab initio studies of advanced functional materials with complex magnetism
Abstract : For centuries, magnetism of materials has been an inevitable part of human civilization. Only in the last century, the mysteries of magnetism started to unfold thanks to the development of quantum theory of solids. READ MORE

9. First-principles Studies of Local Structure Effects in Magnetic Materials
Abstract : This thesis focus on the magnetic behavior, from single atoms to bulk materials. The materials considered in this thesis have been studied by computational methods based on ab initio theory, density functional theory (DFT), including treatment of the spin-orbit coupling, non-collinear magnetism, and methods capable of treating discorded systems.

10. Electronic Transport in Materials
Abstract : Transport properties within the Boltzmann transport equation for metallic multi-layer structures as well as bulk materials, were the prime topic of this work. Ab initio total energy calculations for Hydrogen loaded metallic multi-layers were performed in order to shed some light onto problem of H depleted layers at the interfaces that have been experimentally observed.
