“…This effect was predicted theoretically in the '70s 3,4 for a two-dimensional electron gas (2DEG) with Rashba spinorbit interaction, and then it was studied in various systems exhibiting spin-orbit interaction [5][6][7][8][9][10][11][12][13] . The currentinduced spin polarization was also observed experimentally 14 , and currently it is attracting attention of many researchers [15][16][17][18][19][20][21][22] . The current-induced spin polarization can also arise in a magnetic system, when it includes spin-orbit coupling.…”
Current-induced spin polarization in a two-dimensional electron gas with Rashba spin-orbit interaction is considered theoretically in terms of the Matsubara Green functions. This formalism allows to describe temperature dependence of the induced spin polarization. The electron gas is assumed to be coupled to a magnetic substrate via exchange interaction. Analytical and numerical results on the temperature dependence of spin polarization have been obtained in the linear response regime. The spin polarization has been presented as a sum of two terms -one proportional to the relaxation time and the other related to the Berry phase corresponding to the electronic bands of the magnetized Rashba gas. The spin-orbit torque due to Rashba interaction is also discussed. Such a torque appears as a result of the exchange coupling between the non-equilibrium spin polarization and magnetic moment of the underlayer.

“…The analysis of published materials shows that the theoretical papers about nonstationary electrokinetic processes are not numerous, and they deal mainly with the so-called quasi-stationary regimes, which are the periodical flow regimes originated by the action of a sinusoidal electric field [1][2][3][4][5][6][7][8] or a sinusoidal pressure gradient [9][10][11]. Also, papers investigating the application of an electroacoustic field [12] and the measurement of dielectric dispersion to the study of disperse systems fall into this category [13][14][15][16].…”
A theoretical model of the EOF established in a wide capillary after the application of a stepwise voltage has been developed. Both periodical and aperiodical flow regimes were studied with arbitrary pulse/pulse or pulse/pause durations and amplitudes. The numerical analysis performed for a few types of periodical regimes showed the peculiarities of the profiles of liquid velocity and its displacement both for the transition to the stationary regime and for the quasi-stationary periodical and aperiodical regimes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
