  2. 6. 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

  4. 7. Magnetization Dynamics in Ferromagnetic Thin Films : Evaluation of Different Contributions to Damping in Co2FeAl and FeCo Film Structures

    Author : Serkan Akansel; Peter Svedlindh; Olof Karis; Erik Wahlström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spintronics; Gilbert damping parameter; magnetization dynamics; ferromagnetic resonance; Heusler alloys; magnetic thin films; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Static and dynamic magnetic properties of Co2FeAl and Fe65Co35 alloys have been investigated. Co2FeAl films were deposited at different temperatures and the deposition parameters were optimized with respect to structural and magnetic properties. As a result, a film with B2 crystalline phase was obtained without any post-annealing process. READ MORE

  5. 8. Modulating magnetic interactions : in metamaterials and amorphous alloys

    Author : Nanny Strandqvist; Björgvin Hjörvarsson; Alexei Vorobiev; Sean Langridge; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; interlayer exchange coupling; superlattice; mesospins; magnetic nanostructures; emergence; amorphous alloys; CoAlZr; FeZr; Fysik; Physics;

    Abstract : This thesis is focused on exploring and modulating magnetic interactions in metamaterials and amorphous alloys along one-, two-, and three-dimensions. First, thin films of alternating Fe and MgO are adapted to modulate magnetic interactions along one dimension. READ MORE

  6. 9. Metallic Amorphous Thin Films and Heterostructures with Tunable Magnetic Properties
