Giant spin splitting through surface alloying.
The long-range ordered surface alloy Bi/Ag(111) is found to exhibit a giant spin splitting of its surface electronic structure due to spin-orbit coupling, as is determined by angle-resolved… Expand
Magnetic anisotropy and magnetization dynamics of individual atoms and clusters of Fe and Co on Pt(111).
The recently discovered giant magnetic anisotropy of single magnetic Co atoms raises the hope of magnetic storage in small clusters. We present a joint experimental and theoretical study of the… Expand
Quantitative analysis of clumps in the tidal tails of star clusters
Tidal tails of star clusters are not homogeneous but show well-defined clumps in observations as well as in numerical simulations. Recently, an epicyclic theory for the formation of these clumps was… Expand
Prediction and observation of an antiferromagnetic topological insulator
Magnetic topological insulators are narrow-gap semiconductor materials that combine non-trivial band topology and magnetic order1. Unlike their nonmagnetic counterparts, magnetic topological… Expand
Stabilizing the magnetic moment of single holmium atoms by symmetry
Single magnetic atoms, and assemblies of such atoms, on non-magnetic surfaces have recently attracted attention owing to their potential use in high-density magnetic data storage and as a platform… Expand
Self-interaction correction in multiple scattering theory
We propose a simplified version of self-interaction corrected local spin-density (SIC-LSD) approximation, based on multiple scattering theory, which implements self-interaction correction locally,… Expand
Exchange coupling in transition metal monoxides: Electronic structure calculations
An ab initio study of magnetic-exchange interactions in antiferromagnetic and strongly correlated 3d transition metal monoxides is presented. Their electronic structure is calculated using the local… Expand
Different dimensionality trends in the Landau damping of magnons in iron, cobalt and nickel: time dependent density functional study
We study the Landau damping of ferromagnetic magnons in Fe, Co, and Ni as the dimensionality of the system is reduced from three to two. We resort to theab initio linear response time dependent… Expand

In order to gain insight into the so-called d(0)-magnetic properties of defective ZnO we have carried out first principles calculations on various types of defects formed by intrinsic defects and… Expand

We present a combined experimental and theoretical study of the interplay between the atomic structure and the magnon excitations in low dimensional ferromagnets. Two monolayer thick Fe films on… Expand
