Magnetism of metal-free graphene-based materials
(Lappeenranta-Lahti University of Technology LUT, 2021-12-09)
In the present work, the magnetic properties of several carbon materials were investigated. The materials are sp2 carbon allotropes, the magnetic properties of which are determined by intrinsic carbon properties or are ...
Properties of exchange interactions in magnetic semiconductors
(Lappeenranta-Lahti University of Technology LUT, 2020-12-02)
This dissertation is devoted to the investigation of magnetic properties of nanostructures with magnetic impurities. The properties of electron spin relaxation in magnetically doped quantum well was investigated. It has ...
Interplay of local moments and itinerant electrons
(Lappeenranta-Lahti University of Technology LUT, 2020-10-02)
We have studied the electronic structure of materials whose properties are driven by magnetism. This work requires research with computer simulations based on quantum mechanics laws within the density functional theory ...
