Dynamical Magnetic Excitations of Nanostructures from First Principles

Abstract: Within time-dependent density functional theory, combined with the Korringa-Kohn-Rostoker Green functions, we devise a real space method to investigate spin dynamics. Our scheme enables one to deduce the Coulomb potential which assures a proper Goldstone mode is present. We illustrate with application to 3d adatoms and dimers on Cu(100).

“…Fig. 2(a) shows our calculations of the resonant response of the local moments for four adatoms on this surface [28,29]. If an external static magnetic field is applied along the initial direction of the magnetic moments, we expect from a Heisenberg model a delta function in the excitation spectrum located at the Larmor frequency, ω L = gB ext .…”

“…[28,29] we presented a computationally attractive method that allows us to address magnetic excitations from first-principles. We use the Korringa-Kohn-Rostoker (KKR) single particle Green function (GF) [31] which contains an ab-initio description of the electronic structure.…”
