  4. 12. Magnetism and Structure in Metallic Multilayers

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 14. Growth of Ag/Ni Thin Films and Multilayers

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

    Abstract : 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. READ MORE

  7. 15. Spin Vortices, Interlayer Exchange, and Magnetocalorics in Multilayers

    Author : Milton Persson; Vladislav Korenivski; David B. Haviland; Coriolan Tiusan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin vortex pairs; bimerons; RKKY; finite size effects; nanostructure magnetocalorics; atomistic spin dynamics; nanocalorimetry; Spinvirvelpar; bimeron; RKKY; finita storlekseffekter; magnetkalorimetri i nanostrukturer; atomistisk spindynamik; nanokalorimetri; Material and Nano Physics; Material- och nanofysik;

    Abstract : In this thesis we study strongly coupled pairs of spin vortices, in a configurationsuch that the cores attract while external fields act to pull them apart, with potential applications in magnetic random access memory (MRAM) and oscillators.Inertial decoupling of the cores has been studied and can be achieved with weak nanosecond pulses by the help of anharmonicity.
