First-principles dynamical spin and charge currents in magnetic nanostructures — •Sascha Brinker, Filipe Souza Mendes Guimarães, Manuel dos Santos Dias, and Samir Lounis — Peter Grünberg Institut and Institute for Advanced Simulation, Forschungszentrum Jülich and JARA, D-52425 Jülich, Germany

We investigate the spatial distribution of ground state and dynamical spin and charge currents in magnetic nanostructures from first-principles. We outline our density functional theory implementation in the Korringa-Kohn-Rostoker Green function method, in a real-space approach. Small magnetic nanostructures are considered, e.g. Fe adatoms, dimers and trimers on the Au(111) and Pt(111) surfaces. Our findings should be relevant for recent and future microscopy techniques [1].
