TLDR
In this paper, the authors proposed a spin-interference device which works even without any ferromagnetic electrodes and any external magnetic field, which can be expected in the AB ring with a uniform spin-orbit interaction, which causes the phase difference between the spin wave functions traveling in the clockwise and anticlockwise direction.Abstract:
We propose a spin-interference device which works even without any ferromagnetic electrodes and any external magnetic field. The interference can be expected in the Aharonov–Bohm (AB) ring with a uniform spin-orbit interaction, which causes the phase difference between the spin wave functions traveling in the clockwise and anticlockwise direction. The gate electrode, which covers the whole area of the AB ring, can control the spin-orbit interaction, and therefore, the interference. A large conductance modulation effect can be expected due to the spin interference.read more

TL;DR: In this paper, it was shown that spin polarization can also be achieved without the need for magnetism by using the unique crystal symmetry of tungsten selenide, which creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.

Spin-polarized supercurrents for spintronics: a review of current progress.
TL;DR: In this article, the authors describe the controlled creation of long-range equal-spin triplet supercurrents in ferromagnets and their contribution to spintronics, which is a fruitful basis for the study of fundamental physics as they combine macroscopic quantum coherence with microscopic exchange interactions.

Spin interference effects in ring conductors subject to Rashba coupling
Diego Frustaglia,Klaus Richter +1 more
TL;DR: In this paper, the spin-induced modulation of unpolarized currents as a function of the Rashba spin-orbit coupling strength was studied. And the authors showed that the polarization direction of initially polarized, transmitted spins can be tuned via an additional small magnetic control flux.

TL;DR: In this article, the authors associate nonmonotonic phase changes with the Aharonov-Casher effect, which is confirmed by comparison with numerical calculations of the magnetoconductance for a multichannel ring structure within the Landauer-Buttiker formalism.

Oscillatory effects and the magnetic susceptibility of carriers in inversion layers
TL;DR: In this paper, the spin-orbit interaction Hamiltonian HSO = alpha ( sigma *k) was used to change the usual patterns of B-1-periodic oscillations; some oscillations are strongly suppressed due to the diminishing of the gaps between adjacent levels and new oscillations appear due to intersections of levels.

Experimental and theoretical approach to spin splitting in modulation-doped In x Ga 1 − x As/InP quantum wells for B→0
TL;DR: In this article, a gate on top of a Hall bar was used to modify the strength of the spin-orbit coupling, which was quantitatively explained by utilizing a refined envelope function approximation theory for heterostructures.
