Spin Currents in Metallic Nanostructures; Explicit Calculations
F. S. M. Guimarães, A. T. Costa, R. B. Muniz +1
In ultrathin ferromagnets deposited on metallic substrates, excitation of precessional motion of the spins produces a spin current in the substrate that transports angular momentum…
Anomalously large g-factor of single atoms adsorbed on a metal substrate
B. Chilian, A. A. Khajetoorians, S. Lounis +4
We have performed inelastic scanning tunneling spectroscopy (ISTS) on individual Fe atoms adsorbed on a Ag(111) surface. ISTS reveals a magnetization excitation with a lifetime of…
Itinerant Nature of Atom-Magnetization Excitation by Tunneling Electrons
Alexander Ako Khajetoorians, Samir Lounis, Bruno Chilian +5
We have performed single-atom magnetization curve (SAMC) measurements and inelastic scanning tunneling spectroscopy (ISTS) on individual Fe atoms on a Cu(111) surface. The SAMCs sh…
Theory of Local Dynamical Magnetic Susceptibilities from the Korringa-Kohn-Rostoker Green Function Method
S. Lounis, A. T. Costa, R. B. Muniz +1
Within the framework of time-dependent density functional theory combined with the Korringa-Kohn-Rostoker Green function formalism, we present a real space methodology to investiga…
Spin Orbit Coupling and Spin Waves in Ultrathin Ferromagnets: The Spin Wave Rashba Effect
A. T. Costa, R. B. Muniz, S. Lounis +2
We present theoretical studies of the influence of spin orbit coupling on the spin wave excitations of the Fe monolayer and bilayer on the W(110) surface. The Dzyaloshinskii-Moriya…
Carbon nanotube: a low-loss spin-current waveguide
F. S. M. Guimarães, D. F. Kirwan, A. T. Costa +3
We demonstrate with a quantum-mechanical approach that carbon nanotubes are excellent spin-current waveguides and are able to carry information stored in a precessing magnetic mome…
