Possible d0 ferromagnetism in MgO doped with nitrogen
Bo Gu, Nejat Bulut, Timothy Ziman +1
We study the possibility of d0 ferromagnetism in the compound MgO doped with nitrogen (N). The Haldane-Anderson impurity model is formulated within the tight-binding approximation…
Enhanced spin Hall effect by resonant skew scattering in orbital-selective Kondo effect
Guang-Yu Guo, Sadamichi Maekawa, Naoto Nagaosa
The enhanced spin Hall effect in Au metal due to the resonant skew scattering is studied with first-principles band structure calculations. Especially the gigantic spin Hall angle…
Inter-impurity and impurity-host magnetic correlations in semiconductors with low-density transition-metal impurities
Yoshihiro Tomoda, Nejat Bulut, Sadamichi Maekawa
Experiments on (Ga,Mn)As in the low-doping insulating phase have shown evidence for the presence of an impurity band at 110 meV above the valence band. The motivation of this paper…
Effects of the crystal structure on the ferromagnetic correlations in ZnO with magnetic impurities
Bo Gu, Nejat Bulut, Sadamichi Maekawa
We study the ferromagnetism in the compound (Zn,Mn)O within the Haldane-Anderson impurity model by using the quantum Monte Carlo technique and the tight-binding approximation for d…
Kondo effect in quantum dots coupled to ferromagnetic leads with noncollinear magnetizations: effects due to electron-phonon coupling
R. Swirkowicz, M. Wilczynski, J. Barnas
Spin-polarized transport through a quantum dot strongly coupled to ferromagnetic electrodes with non-collinear magnetic moments is analyzed theoretically in terms of the non-equili…
Enhancement of phonon effects in photoexcited states of one-dimensional Mott insulators
Hiroaki Matsueda, Akihiro Ando, Takami Tohyama +1
We examine how the electron correlation affects the electron-phonon (EP) interaction in the linear optical absorption spectrum of the one-dimensional (1D) extended Hubbard-Holstein…
