Perfect flat band with chirality and charge ordering out of strong spin-orbit interaction

open access: yesNature Communications, 2022
Spin-orbit coupling has been typically associated with dispersion and topological character of electronic bands. Here, the authors show analytically that strong spin orbit coupling can lead to ultra-flat bands with strong correlations in a 5d pyrochlore ...

Spin-orbit coupling and electron correlation effects on phonon anharmonicity of KOs2O6

open access: yesAIP Advances, 2019
Spin-orbit coupling and electron correlation effects from Os 5d electrons on phonon anharmonicity of β−pyrochlore superconductor KOs2O6 are systematically studied by first-principles frozen-phonon calculations.

Zeeman spin-orbit coupling in antiferromagnetic conductors

open access: yes, 2018
This article is a brief review of Zeeman spin-orbit coupling, arising in a low-carrier commensurate N\'eel antiferromagnet subject to magnetic field. The field tends to lift the degeneracy of the electron spectrum.

Magnetic ordering phenomena of interacting quantum spin Hall models

open access: yes, 2012
The two-dimensional Hubbard model defined for topological band structures exhibiting a quantum spin Hall effect poses fundamental challenges in terms of phenomenological characterization and microscopic classification. In the limit of infinite coupling U

Theory of anisotropic exchange in laterally coupled quantum dots [PDF]

open access: yes, 2010
The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence of magnetic field the exchange interaction is practically unaffected by ...

Spin–torque generator engineered by natural oxidation of Cu

open access: yesNature Communications, 2016
In thin film spintronic devices, heavy metals with strong spin-orbit coupling are required to achieve a sizeable spin Hall effect. Here, the authors demonstrate an enhancement of the spin Hall effect in Cu, a material with weak spin-orbit coupling, via ...

Spin structure factors of doped monolayer Germanene in the presence of spin-orbit coupling

open access: yesScientific Reports, 2021
In this paper, we present a Kane-Mele model in the presence of magnetic field and next nearest neighbors hopping amplitudes for investigations of the spin susceptibilities of Germanene layer.

Origin of enhanced anomalous Hall effect in ultrathin Pt/permalloy bilayers

open access: yesAIP Advances, 2016
There are two mechanisms which could enhance spin-dependent scattering in a low dimensional Pt/Ferromagnetic metal structure. One is magnetic proximity effect. The other is spin orbit coupling proximity effect which was suggested recently.

Current-induced spin polarization for a general two-dimensional electron system

open access: yes, 2009
In this paper, current-induced spin polarization for two-dimensional electron gas with a general spin-orbit interaction is investigated. For isotropic energy spectrum, the in-plane current-induced spin polarization is found to be dependent on the ...

Variation of spin–orbit coupling and related properties in skyrmionic system Mn FexGe

open access: yesNew Journal of Physics, 2016
We report a systematic study of the magnetic and magnetotransport properties in skyrmionic compounds Mn ${}_{1-x}$ Fe _x Ge. Helical-spin or skyrmion orders are formed in all the compositions, which allows us to study electron band-filling dependence of ...
