  2. 1. The Importance of Controlling Composition to Tailor the Properties of Magnetic Thin Films

    Author : Andreas Frisk; Gabriella Andersson; Tomas Nyberg; Erik Johansson; Sarah Thompson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; FeNi; L10; X-ray diffraction; magnetic anisotropy; magnetron sputtering; thin film; permanent magnets; combinatorial materials science; amorphous materials; magnetic properties of thin films; chemical order; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Many physical properties, for example structural or magnetic, of a material are directly dependent on elemental composition. Tailoring of properties through highly accurate composition control is possible in thin films. This work exemplifies such tailoring. READ MORE

  5. 3. Growth and Magnetic Properties of Fe- and FeNi-based Thin Films and Multilayers

    Author : Anna Maria Blixt; Björgvin Hjörvarsson; Gabriella Andersson; Panagiotis Poulopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Sputter growth; Permalloy; Multilayer; Superlattice; Magnetism; Fysik; Physics; Fysik;

    Abstract : This thesis concerns the growth and magnetic properties of thin films and multilayers. The samples were grown by magnetron sputtering, and characterized structurally mainly by x-ray diffraction and reflectivity. READ MORE

  6. 4. Magnetism of Semiconductors and Metallic Multilayers

    Author : Victor Stanciu; Per Nordblad; Peter Svedlindh; Poul Erik Lindelof; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Magnetic order; Curie temperature; magnetic anisotropy; diluted magnetic III-V semiconductors; metallic magnetic multilayers; interlayer exchange coupling; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Magnetic properties of diluted magnetic semiconductors and magnetic metallic multilayers are investigated by SQUID magnetometry. By doping GaAs with magnetic Mn2+ ions under well defined growth conditions, one obtains a diluted magnetic semiconductor, (Ga,Mn)As, in which the randomly-distributed magnetic ions act as acceptor centers.

  7. 5. Atom probe tomography of Zircaloy-2 exposed to boiling water reactor operation

    Author : Johan Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear fuel claddings; Zirconium alloys; Boiling water reactor; Clustering; Atom probe tomography; Radiation effects; Zircaloy-2; Dislocation loops;

    Abstract : Zirconium alloys are used as cladding tubes for the fuel in nuclear reactors. In boiling water reactors (BWRs), the alloy Zircaloy-2, which contains the alloying elements Sn, Fe, Cr, Ni, and O, is commonly used. READ MORE
