Isotropic spin polarization in Heusler Co2FeAl thin films
AIP Advances, 2022 Spin polarization and the Gilbert damping, as the two key parameters of the magnetic materials for spintronic applications, were suggested to be inversely proportional to each other in a series of Heusler alloys.

Field-free magnetization switching induced by the unconventional spin–orbit torque from WTe2
APL Materials, 2021 Spin–orbit torque provides a highly efficient way to achieve current-induced magnetization switching, which relies on charge-to-spin conversion of the spin source layer.

Polarization versus photon spin [PDF]
Optics Express, 2014 We examine whether the Stokes parameters of a two-mode electromagnetic field results from the superposition of the spins of the photons it contains. To this end we express any n-photon state as the result of the action on the vacuum of n creation operators generating photons which can have may different polarization states in general.

All‐Electric Spin Device Operation Using the Weyl Semimetal, WTe2, at Room Temperature
Advanced Electronic Materials, 2023 Topological quantum materials (TQMs) possess abundant and attractive spin physics, and a Weyl semimetal is the representative material because of the generation of spin polarization that is available for spin devices due to its Weyl nature.

Topological spin textures of exciton-polaritons manipulating by spin-orbit coupling
Results in Optics, 2021 The topological spin textures of exciton-polariton in microcavities are governed by the interplay of the spin-orbit coupling and longitudinal-transverse splitting.

When measured spin polarization is not spin polarization
Journal of Physics: Condensed Matter, 2011 Spin polarization is an unusually ambiguous scientific idiom and, as such, is rarely well defined. A given experimental methodology may allow one to quantify a spin polarization but only in its particular context. As one might expect, these ambiguities sometimes give rise to inappropriate interpretations when comparing the spin polarizations determined

Spin polarization induced by decoherence in a tunneling one-dimensional Rashba model
SciPost Physics Core, 2023 Basic questions on the nature of spin polarization in two terminal systems and the way in which decoherence breaks Time-Reversal Symmetry (TRS) are analyzed. We exactly solve several one-dimensional models of tunneling electrons and show the interplay of

Focusing of Spin Polarization in Semiconductors by Inhomogeneous Doping [PDF]
, 2003 We study the evolution and distribution of non-equilibrium electron spin polarization in n-type semiconductors within the two-component drift-diffusion model in an applied electric field. Propagation of spin-polarized electrons through a boundary between
