Hysteretic behavior in weakly coupled double-dot transport in the spin blockade regime
J. Inarrea, C. Lopez-Monis, A. H. MacDonald +1
Double quantum dot systems in the spin blockade regime exhibit leakage currents that have been attributed to the Hyperfine interaction. We model weakly coupled double-dot transport…
Coordinate shift in the semiclassical Boltzmann equation and the anomalous Hall effect
N. A. Sinitsyn, Q. Niu, A. H. MacDonald
We propose a gauge invariant expression for the side jump associated with scattering between particular Bloch states. Our expression for the side jump follows from the Born series…
Edge spin accumulation in semiconductor two-dimensional hole gases
K. Nomura, J. Wunderlich, Jairo Sinova +3
The controlled generation of localized spin densities is a key enabler of semiconductor spintronics In this work, we study spin Hall effect induced edge spin accumulation in a two-…
Experimental observation of the spin-Hall effect in a two dimensional spin-orbit coupled semiconductor system
Joerg Wunderlich, Bernd Kaestner, Jairo Sinova +1
We report the experimental observation of the spin-Hall effect in a two-dimensional (2D) hole system with Rashba spin-orbit coupling. The 2D hole layer is a part of a p-n junction…
Semiclassical theory of spin transport in spin-orbit coupled systems
Dimitrie Culcer, Jairo Sinova, N. A. Sinitsyn +3
Motivated by recent interest in novel spintronics effects, we develop a semiclassical theory of spin transport that is valid for spin-orbit coupled bands. Aside from the obvious co…
Magnetization relaxation in (Ga,Mn)As ferromagnetic semiconductors
Jairo Sinova, T. Jungwirth, X. Liu +4
We describe a theory of Mn local-moment magnetization relaxation due to p-d kinetic-exchange coupling with the itinerant-spin subsystem in the ferromagnetic semiconductor (Ga,Mn)As…
Resistance spikes and domain wall loops in Ising quantum Hall ferromagnets
T. Jungwirth, A. H. MacDonald
We explain the recent observation of resistance spikes and hysteretic transport properties in Ising quantum Hall ferromagnets in terms of the unique physics of their domain walls.…
Pseudospin Anisotropy Classification of Quantum Hall Ferromagnets
T. Jungwirth, A. H. MacDonald
Broken symmetry ground states with uniform electron density are common in quantum Hall systems when two Landau levels simultaneously approach the chemical potential at integer fill…
