   Author : Alexander Edström; Jan Rusz; Olle Eriksson; Patrick Bruno; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Magnetic anisotropy; DFT; Permanent magnets; Electron vortex beams; Electron microscopy; Electron scattering; Multislice methods; Magnetism; magnetisk anisotropi; permanentmagneter; täthetsfunktionalteori; elektronmikroskopi; elektronvirvelstrålar; elektronspridningsteori; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : In this thesis, two selected topics in magnetism are studied using theoretical modelling and computational methods. The first of these is the magnetocrystalline anisotropy energy (MAE) of transition metal based magnets. In particular, ways of finding 3d transition metal based materials with large MAE are considered. READ MORE

4. 2. Theoretical Magnet Design : From the electronic structure of solid matter to new permanent magnets

   Author : Alexander Edström; Jan Rusz; Olle Eriksson; Ingo Opahle; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : A good permanent magnet should possess a large saturation magnetisation (Ms), large mag- netocrystalline anisotropy energy (MAE) and a high Curie temperature (TC). A difficult but important challenge to overcome for a sustainable permanent magnet industry is to find novel magnetic materials, exhibiting a large MAE, without the use of scarcely available elements such as rare-earth metals.
