Computational Magnetism
The research portfolio of the Computational Magnetism Research Group includes the theoretical and computational investigations of magnetic phenomena in bulk alloys, heterostructures and nanoparticles. Our studies are based on relativistic ab-initio calculations: we either use ab-initio spin-dynamics to determine the magnetic structure or we compute the parameters of a suitable spin model, then we study the magnetization processes via Monte-Carlo and spin-dynamics simulations. We mainly focus on the complex magnetic pattern formation and magnetic excitations in ultrathin films, with special emphasis on magnetic skyrmions. Moreover, we study the superparamagnetism of magnetic nanoparticles, as well as the topological quantum states in magnetic clusters placed on the surface of superconductors. Within a broad international cooperation, we aim at contributing to the innovation in the modern magnetic and quantum information technology.
