Single-particle states in spherical Si/SiO quantum dots
A. S. Moskalenko, J. Berakdar, A. A. Prokofiev +1
We calculate ground and excited electron and hole levels in spherical Si quantum dots inside SiO in a multiband effective mass approximation. Luttinger Hamiltonian is used for…
Tunable conductance of magnetic nanowires with structured domain walls
V. K. Dugaev, J. Berakdar, J. Barnas
We show that in a magnetic nanowire with double magnetic domain walls, quantum interference results in spin-split quasistationary states localized mainly between the domain walls.…
Charge-transfer polaron induced negative differential resistance and giant magnetoresistance in organic spintronics: A Su-Schrieffer-Heeger model study
J. H. Wei, S. J. Xie, L. M. Mei +2
Combining the Su-Schrieffer-Heeger model and the non-equilibrium Green's function formalism, we investigate the negative differential resistance effect in organic spintronics at lo…
Current-induced motion of a domain wall in magnetic nanowires
V. K. Dugaev, V. R. Vieira, P. D. Sacramento +3
The dynamics of current-induced motion of a magnetic domain wall in a quasi-one-dimensional ferromagnet with both easy-axis and easy-plane anisotropy, is studied. We pay a special…
Magnetoresistance of a semiconducting magnetic wire with domain wall
V. K. Dugaev, J. Barnas, J. Berakdar +3
We investigate theoretically the influence of the spin-orbit interaction of Rashba type on the magnetoresistance of a semiconducting ferromagnetic nanostructure with a laterally co…
Reflection of electrons from a domain wall in magnetic nanojunctions
V. K. Dugaev, J. Berakdar, J. Barnas
Electronic transport through thin and laterally constrained domain walls in ferromagnetic nanojunctions is analyzed theoretically. The description is formulated in the basis of sca…
