Journal ArticleDOI
Tight-binding approach to the orbital magnetic moment and magnetocrystalline anisotropy of transition-metal monolayers
TL;DR: A perturbative theory of magnetocrystalline anisotropy and orbital moment in itinerant ferromagnets is presented and it is shown that it may produce an an isotropy in the magnetization of the order of 0.1\ensuremath{\mu}B per atom.
Journal ArticleDOI
Oscillatory coupling between ferromagnetic layers separated by a nonmagnetic metal spacer.
Patrick Bruno,C. Chappert +1 more
TL;DR: The expression of the Ruderman-Kittel-Kasuya-Yosida coupling between two ferromagnetic layers separated by a nonmagnetic spacer is derived and quantitative predictions of the interlayer coupling for Cu, Ag, and Au spacers are given.
Journal ArticleDOI
Giant spin splitting through surface alloying.
Christian R. Ast,Christian R. Ast,Juergen Henk,Arthur Ernst,Luca Moreschini,Mihaela C. Falub,Daniela Pacilé,Patrick Bruno,Klaus Kern,Klaus Kern,Marco Grioni +10 more
TL;DR: 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 photoelectron spectroscopy.
Journal ArticleDOI
Theory of interlayer magnetic coupling
TL;DR: A theory of interlayer exchange coupling is presented and the cases of metallic and insulating spacers are treated in a unified manner by introducing the concept of the complex Fermi surface.
Journal ArticleDOI
Topological Hall effect and Berry phase in magnetic nanostructures.
TL;DR: The anomalous Hall effect in a two-dimensional electron gas subject to a spatially varying magnetization is discussed and an experiment with a structure containing 2D electrons or holes of diluted magnetic semiconductor subject to the stray field of a lattice of magnetic nanocylinders is proposed.
