Spin and Charge Shot Noise in Mesoscopic Spin Hall Systems
R. L. Dragomirova, L. P. Zarbo, B. K. Nikolic
Injection of unpolarized charge current through the longitudinal leads of a four-terminal two-dimensional electron gas with the Rashba spin-orbit (SO) coupling and/or SO scattering…
Hybrid skew scattering regime of the anomalous Hall effect in Rashba systems: unifying Keldysh, Boltzmann, and Kubo formalisms
Alexey A. Kovalev, Karel Výborný, Jairo Sinova
We present the analytical description of the anomalous Hall effect (AHE) in a 2DEG ferromagnet within the Keldysh formalism. These results unify all three linear response approache…
Nanomechanical Spin-Polarizer
Alexey A. Kovalev, Liviu P. Zârbo, Y. Tserkovnyak +2
Torsional oscillations of a free-standing semiconductor beam are shown to cause spin-dependent oscillating potentials that spin-polarize an applied charge current in the presence o…
Functional Keldysh Theory of Spin Torques
R. A. Duine, A. S. Nunez, Jairo Sinova +1
We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find…
Phonon-bottleneck enhanced magnetic hysteresis in a molecular paddle wheel complex of Ru
L. Chen, C. M. Ramsey, N. S. Dalal +4
The ruthenium based molecular magnet [Ru(D(3,5-ClPh)F)Cl(0.5HO)CH] (hereafter Ru) behaves as a two-level system at sufficiently low temperatu…
Can Non-Equilibrium Spin Hall Accumulation be Induced in Ballistic Nanostructures?
Branislav K. Nikolic, Satofumi Souma, Liviu P. Zarbo +1
We demonstrate that flow of longitudinal unpolarized current through a ballistic two-dimensional electron gas with Rashba spin-orbit coupling will induce nonequilibrium spin accumu…
