  2. 1. Amorphous Magnetic Materials : A Versatile Foundation for Tomorrow’s Applications

    Author : Sebastian George; Gabriella Andersson; Björgvin Hjörvarsson; Fridrik Magnus; Elizabeth Blackburn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; Magnetism; Rare Earth; Transition Metal; RE-TM; Thin Film; TbCo; SmCo; FeZr; CoFeZr;

    Abstract : Amorphous magnetic materials exhibit a number of key differentiating properties with respect to crystalline magnets. In some cases, the differences may simply be in the values of macroscopic properties such as saturation magnetization, coercivity, Curie temperature, and electrical conductivity. READ MORE

  4. 2. Nucleation and stress generation in thin films deposited with a pulsed energetic deposition flux

    Author : Daniel Magnfält; Ulf Helmersson; Fridrik Magnus; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis presents fundamental mechanisms of nucleation and early growth of and stress generation in thin polycrystalline metal films deposited using pulsed energetic deposition fluxes. The effects of a pulsed deposition flux and energetic bombardment on film nucleation was investigated using in situ stress measurements and in situ ellipsometry to determine the film thickness at which the films become continuous.

  5. 3. Magnetic Properties of Epitaxial Metal/Oxide Heterostructures

    Author : Tobias Warnatz; Björgvin Hjörvarsson; Fridrik Magnus; Vassilios Kapaklis; Stuart S.P. Parkin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fe MgO; interlayer exchange coupling; anisotropy; IEC; superlattice; multilayer; polarized neutron reflectometry; PNR; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The work in this dissertation is devoted to tailoring and studying magnetic properties of epitaxial metal/oxide heterostructures. The aim is to understand the fundamental principles governing these properties and how they affect each other. The acquired knowledge can prove useful for the development of future spintronic devices. READ MORE
