  1. 1. Ab initio studies of advanced functional materials with complex magnetism

    Författare :Duo Wang; Biplab Sanyal; Roland Mathieu; Claude Ederer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Complex magnetism; 2D magnets; Functional material; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : For centuries, magnetism of materials has been an inevitable part of human civilization. Only in the last century, the mysteries of magnetism started to unfold thanks to the development of quantum theory of solids. LÄS MER

  3. 2. Configurational and Magnetic Interactions in Multicomponent Systems

    Författare :Björn Alling; Igor A. Abrikosov; Lars Hultman; Stefan Blügel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic interactions; Configurational thermodynamics; Curie temperature; theoretical physics; magnetism; TiAlN; TiN; AlN; CrN; TiCrN; nitrides; NiMnSb; NiCuMnSb; Heusler alloys; spintronics; half-metallic; spinodal decomposition; first-principles; ab-initio; Magnetism; Magnetism;

    Sammanfattning : This thesis is a theoretical study of configurational and magnetic interactions in multicomponent solids. These interactions are the projections onto the configurational and magnetic degrees of freedom of the underlying electronic quantum mechanical system, and can be used to model, explain and predict the properties of materials.

  4. 3. Magnetization dynamics of complex magnetic materials by atomistic spin dynamics simulations

    Författare :Raghuveer Chimata; Biplab Sanyal; Olle Eriksson; Koopmans Bert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ultrafast remagnetization; ultrafast dynamics; magnetism; multiferroics; amorphous alloys; DFT; spinels magnetostriction; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In recent years, there has been an intense interest in understanding the microscopic mechanism of laser induced ultrafast magnetization dynamics in picosecond time scales. Magnetization switching on such a time scale has potential to be a significant boost for the data storage industry. LÄS MER

  7. 5. Assembly of the Caledonian Orogenic Wedge, Jämtland, Sweden

    Författare :Hagen Bender; Uwe Ring; Bjarne SG Almqvist; Rob Strachan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; collisional orogeny; Scandinavian Caledonides; Seve Nappe Complex; Köli Nappe Complex; in-sequence thrusting; out-of-sequence thrusting; imbrication; nappe stacking; orogenic wedge assembly; Rb–Sr geochronology; rock magnetism; anisotropy of magnetic susceptibility; Geology; geologi;

    Sammanfattning : Collisional orogeny creates the largest mountain belts on Earth. The Caledonides of Scandinavia are a deeply eroded, ancient mountain belt, which today exposes a deep section through the former orogenic interior. LÄS MER
