Alternating spin-polarized current induces parametric resonance in spin valves
(2015)
Ferromagnetic systems under the influence of spin-polarized currents exhibit rich spatiotemporal dynamics at nanoscales. We study spin-transfer nano-oscillators driven by the combination of alternating and direct spin-polarized ...
Anisotropy of the spin-polarized edge current in monolayer transition metal dichalcogenide zigzag nanoribbons
(Amer Physical Soc, 2020-05-15)
We report anisotropic spin polarization of edge currents in MoS2 and WS2 monolayer zigzag nanoribbons (ZNRs) deposited on either nonmagnetic or ferromagnetic insulator substrates. We employ an 11-band tight-binding model ...

Spin polarization in the Hubbard model with Rashba spin-orbit coupling on a ladder
(American Physical Society, 2013-07)
The competition between on-site Coulomb repulsion and Rashba spin-orbit coupling (RSOC) is studied on two-leg ladders by numerical techniques. By studying persistent currents in closed rings by exact diagonalization, it ...

Pure spin current manipulation in antiferromagnetically exchange coupled heterostructures
(American Institute of Physics, 2018-03-28)
We present a model to describe the spin currents generated by ferromagnet/spacer/ferromagnet exchange coupled trilayer systems and heavy metal layers with strong spin-orbit coupling. By exploiting the magnitude of the ...
Spin-polarized current and shot noise in the presence of spin flip in a quantum dot via nonequilibrium Green's functions
(AMER PHYSICAL SOC, 2008)
Using nonequilibrium Green's functions we calculate the spin-polarized current and shot noise in a ferromagnet-quantum-dot-ferromagnet system. Both parallel (P) and antiparallel (AP) magnetic configurations are considered. ...
Current-induced exchange interactions and effective temperature in localized moment systems
(IOP PUBLISHING LTD, 2012-03-21)
We study theoretically the spin dynamics of a magnetic dimer serving as a contact between two electrodes. We find that the spin-spin coupling in the dimer can be dramatically modified from its equilibrium value. We show ...
Spin pumping and inverse spin Hall effect in antiferromagnetic exchange coupled [Co/Ru/Co]/Pt heterostructures
(American Institute of Physics, 2017-01)
We report the observation of spin pumping and inverse spin Hall effects in antiferromagnetically coupled [Co/Ru/Co]/Pt heterostructures. The “spin-flop” magnetization process observed in antiferromagnetically exchange ...
