Influence of nonmagnetic impurity scattering on spin dynamics in diluted magnetic semiconductors
(American Physical Society, 2017-01)
The doping of semiconductors with magnetic impurities gives rise not only to a spin-spin interaction between quasifree carriers and magnetic impurities but also to a local spin-independent disorder potential for the carriers. ...
Laser-dressed-band approach to shallow-impurity levels of semiconductor heterostructures

Effect of an external electric field on local magnetic moments in silicene
(Elsevier Science, 2021-04)
In this work we analyze the effects of the application of an external electric field in the formation of a local magnetic moment in silicene. By adding an impurity in a top site in the host lattice and computing the real ...
Realistic indirect spin interactions between magnetic impurities on a metallic Pb(110) surface
(American Physical Society, 2019-12)
Motivated by recent experiments, here we study the indirect interactions between magnetic impurities deposited on top of a clean Pb(110) surface, induced by the underlying conduction electrons. Our approach makes use of ...
Bulk and surface localized modes on a magnetic nonlinear impurity
(ELSEVIER, 2008-11-17)
We study localized modes on a single magnetic impurity positioned in the bulk or at the surface of a one-dimensional chain, in the presence of a magnetic field 8 acting at the impurity site. The strong on-site nonlinear ...
