Anisotropic spin Hall effect from first principles
Anisotropic spin Hall effect first principles
2010/11/17
We report on first principles calculations of the anisotropy of the intrinsic spin Hall conductivity (SHC) in nonmagnetic hcp metals and in antiferromagnetic Cr. For most of the metals of this study w...
Effect of anisotropy on the field induced quantum critical properties of the three dimensional s=1/2 Heisenberg model
Effect of anisotropy field induced quantum critical properties
2010/11/9
The field induced quantum critical properties of the three dimensional spin-1/2 anisotropic antifer-romagnetic Heisenberg model has been studied. We have investigated the quantum phase transition betw...
Local spin valve effect in lateral (Ga,Mn)As/GaAs spin Esaki diode devices
Local spin valve effect lateral (Ga,Mn)As/GaAs spin Esaki diode devices
2010/11/1
We report here on a local spin valve effect observed unambiguously in lateral all-semiconductor
all-electrical spin injection devices, employing p+−(Ga,Mn)As/n+−GaAs Esaki diode structure...
Spin Soret effect
Spin Soret effect
2010/11/1
Using a three-current model for heat, spin-up and spin-down electrons, the thermodynamics of
irreversible processes predicts that a temperature gradient gives rise to a spin current under the conditi...
Spin Torque Ferromagnetic Resonance Induced by the Spin Hall Effect
Spin Torque Ferromagnetic Resonance Spin Hall Effect
2010/11/1
We demonstrate that the spin Hall effect in a thin film with strong spin-orbit scattering
can excite magnetic precession in an adjacent ferromagnetic film. The flow of alternating current through a P...
Coarsening Kinetics of a Two Dimensional O(2) Ginzburg-Landau Model: Effect of Reversible Mode Coupling
Coarsening Kinetics Two Dimensional O(2) Ginzburg-Landau Model
2010/11/1
We investigate, via numerical simulations, the phase ordering kinetics of a two-dimensional
soft-spin O(2) Ginzburg-Landau model when a reversible mode coupling is included via the
conserved conjuga...
