Kort presentation
Denna text finns inte på svenska, därför visas den engelska versionen.
I study magnetic materials using first principles methods based on density functional theory. For this purpose, I develop computational methods and run simulations, whose outcomes are then directly compared with experiment. The final goal is to be able to predict all the main properties of an arbitrary material, such as its ordering temperature, coercive field or its excitation spectra. I am particularly interested in the magnets with non-collinear ordering and strong electron correlations.
