  4. 13. Magnetism and Structure in Metallic Multilayers

    Författare :Erik Holmström; Turek Ilja; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Magnetism; Interfaces; Structure; KKR-ASA; CPA; Quantum Well; Fysik; Physics; Fysik;

    Sammanfattning : The interplay between magnetism and structure has been studied in magnetic multilayers by electronic structure calculations based on density functional theory and analyzed in terms of models. The main ideas behind the Korringa-Kohn-Rostocker Green’s function method are described and the implementation of the coherent potential approximation is outlined. LÄS MER

  5. 14. Structures of Polyelectrolyte Multilayers and Preasorbed Mucin : The Influence of Counterions

    Författare :Zsombor Feldötö; Eva Blomberg; Regine von Klitzing; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The focus in this thesis has been to gain a fundamental understanding of how different type of salts affect preadsorbed polyelectrolytes, both natural and synthetic. The knowledge from the fundamental work is then applied on a commercial system to investigate if the efficiency can be enhanced. LÄS MER

  7. 15. Growth of Ag/Ni Thin Films and Multilayers

    Författare :Per Sandström; Jørgen Bøttiger; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fundamental studies concerning the relation between growth conditions, microstructure and internal stresses of polycrystalline Ag/Ni thin films and multilayers, as well as the relation between growth conditions and the structure of highly oriented Ni films, were performed. All films were depositied using ultra high vacuum based de magnetron sputtering. LÄS MER
