  2. 6. Lattice dynamics : From fundamental research to practical applications

    Author : Johan Tidholm; Igor A. Abrikosov; Olle Hellman; Ferenc Tasnadi; Gerd Steinle-Neumann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. READ MORE

  4. 7. Theoretical Description of the Electron-Lattice Interaction in Molecular and Magnetic Crystals

    Author : Elham Mozafari; Igor A. Abrikosov; Sven Stafström; George Malcolm Stocks; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular crystals; Charge transport; Polaron; Magnetic materials; Paramagnetic state; Molecular dynamics;

    Abstract : Electron-lattice interactions are often considered not to play a major role in material's properties as they are assumed to be small, the second-order effects. However, this study shows the importance of taking these effects into account in the simulations. READ MORE

  5. 8. Influence of Global Composition and Local Environment on the Spectroscopic and Magnetic Properties of Metallic Alloys

    Author : Weine Olovsson; Igor A. Abrikosov; G. Malcolm Stocks; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; core level shift; random alloy; first principles simulations; density functional theory; auger kinetic energy; Invar alloys; exchange parameter; classical Heisenberg Hamiltonian; complete screening; transition state; disorder broadening; Fysik; Physics; Fysik;

    Abstract : Theoretical investigations of spectroscopic and magnetic properties of metallic systems in the bulk, as well as in nanostructured materials, have been performed within the density functional theory. The major part of the present work studies the differences between binding energies of electrons tightly bound to the atoms, the so-called core electrons (in contrast with the valence electrons), that is, core-level binding energy shift (CLS).

  6. 9. Tailoring Properties of Materials at the Nanoscale

    Author : Hossein Raanaei; Björgvin Hjörvarsson; Igor A. Abrikosov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multilayers; magnetic anysotropy; amorphous materials; Magnetism; Magnetism; Materiefysik; Physics of Matter;

    Abstract : The knowledge of growth and characterizing techniques is essential for the preparation of high quality thin films and multilayers. Here, structural properties have been investigated by X-ray reflectivity, X-ray diffraction, and transmission electron microscopy while the composition was determined by Rutherford backscattering spectrometry.

  7. 10. Thermal Expansion and Local Environment Effects in Ferromagnetic Iron-Based Alloys : A Theoretical Study

    Author : François Liot; Igor Abrikosov; Peter Mohn; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The Nobel Prize for Physics 1920 was awarded to C.-E. Guillaume for his discovery of properties of nickel steels. He had previously observed that certain iron-nickel alloys exhibit the Invar effect i. READ MORE
