An ionic Hamiltonian based on the first Hund rule applied to transition metal atoms is reviewed and discussed in detail. The tunneling current between a STM-tip and a transition metal atom is analyzed by means of that ...

Atheoretical description of the measured differential conductance through magnetic atoms on a Cu2N/Cu(100) substrate is presented [Otte et al., Phys. Rev. Lett. 103, 107203 (2009)]. In particular, we analyze the case of ...

Inelastic electron tunneling spectroscopy (IETS) within the junction of a scanning tunneling microscope (STM) uses current-driven spin-flip excitations for an all-electrical characterization of the spin state of a single ...

The interaction between a single magnetic atom and the metal environment (including a magnetic field) is analyzed by introducing an ionic Hamiltonian combined with an effective crystal-field term, and by using a Green-function ...

Inelastic spin excitations, as observed with a scanning tunneling microscope for Co/Co and Fe/Fe dimers on a Cu2N/Cu(100) surface, have been analyzed theoretically in this paper. In our approach, we use an extended ionic ...

Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphene. Moreover, it was suggested that under ...

Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays important roles, such as in the stabilization ...

Metallorganic molecules have been proposed as excellent spin filters in molecular spintronics because of the large spin polarization of their electronic structure. However, most of the studies involving spin transport have ...
