Transmission of correlated electrons through sharp domain walls in magnetic nanowires: a renormalization group approach
M. A. N. Araujo, V. K. Dugaev, V. R. Vieira +2
The transmission of correlated electrons through a domain wall in a ferromagnetic one dimensional system is studied theoretically in the limit of a domain wall width smaller or com…
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…
Revivals, collapses and magnetic-pulse generation in quantum rings
A. S. Moskalenko, A. Matos-Abiague, J. Berakdar
Using a microscopic theory based on the density matrix formalism we investigate quantum revivals and collapses of the charge polarization and charge current dynamics in mesoscopic…
Role of electron correlations in transport through domain walls in magnetic nanowires
M. A. N. Araujo, V. K. Dugaev, V. R. Vieira +2
The transmission of correlated electrons through a domain wall in ferromagnetic quasi-one-dimensional systems is studied theoretically in the case when the domain wall width is com…
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.…
