16. Magnetic Ordering in Layered Magnets
Abstract : 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. READ MORE

17. 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

18. Phase Transitions and Phase Formation of Hydrogen in Quasi-2D Lattices
Abstract : The role of the dimensionality and strain state of metallic lattices on the phase behavior of dissolved hydrogen was explored. Metallic superlattices with well defined hydrogen absorption potential on the nm scale, were utilized as test systems. READ MORE

19. Influence of Self-trapping, Clamping and Confinement on Hydrogen Absorption
Abstract : The dissociation of hydrogen molecules at surfaces is the first step in the absorption process. If the absorbing material is covered by an oxide, this layer will determine the effective uptake rate of an underlying absorbing material. READ MORE

20. The Influence of Interlayer Exchange Coupling on Magnetic Ordering in Fe-based Heterostructures
Abstract : Temperature dependent magnetization measurements were conducted on Fe-based heterostructures. A linear increase of the magnetic critical temperature with increasing Fe thickness was found for Fe/V superlattices with strong interlayer exchange coupling. READ MORE
