[en] Highlights: • The interfacial spin polarization are modulated by the interfacial angle. • Spin polarization is determined by p_z-d hybridization and sp³-d hybridization. • Angle dependence of p_z-d hybridization and sp³-d hybridization is revealed. Based on ab initio theory, we theoretically investigated the interfacial spin polarization by adsorbing a benzene-dithiolate molecule onto a nickel surface with different interfacial angles. A variable magnitude and even an inversion of the interfacial spin polarization are observed with the increase of the interfacial angle. The orbital analysis shows that the interfacial spin polarization is codetermined by two kinds of orbital hybridization between the molecule and the ferromagnet, the p_z-d hybridization and the sp³-d hybridization, which show different dependence on the angle. These results indicate a new way to manipulate the spin polarization at organic spinterface.

[en] It is shown that the Rashba spin–orbit coupling induces the spatially nonuniform spin state in the square-shaped 1D wire. The electron states of this type are characterized with spin orientation changing according to the harmonic motion along the square side. The period of the oscillation is determined only by the spin–orbital coupling and the hopping parameters ratio. The modulation of spin orientation is caused by step-like changing of Rashba field direction. The obtained results were generalized on the case of polygon-shaped wire.

[en] Highlights: • Both Al and Nb vacancies could induce ferromagnetism in Sr₂AlNbO₆. • Ferromagnetism driven by Al vacancy originates from the 2p_x state of nearest O atoms. • Ferromagnetism induced by Nb vacancy comes from 2p_y and 2p_z states of nearest O atoms. • Sr₂AlNbO₆ with O vacancy is energetically more favorable than with others. - Abstract: Based on first-principles calculation the change of structural, energetic, magnetic and electronic properties of double perovskite oxide Sr₂AlNbO₆ is investigated by introducing intrinsic vacancies. Calculated results show that although both Al and Nb vacancies could induce ferromagnetism the nature of induced ferromagnetism is different. Ferromagnetism driven by Al vacancies originates from the remarkably spin-polarized 2p_x state of nearest O atoms, whereas that induced by Nb vacancy mainly comes from the partially filled spin-polarized 2p_y and 2p_z states of nearest O atoms. Sr₂AlNbO₆ with O vacancy is nonmagnetic but energetically more favorable than that with the other three vacancies

[en] We report a theoretical study on the spin and electron transport in the nonlocal lateral spin valve with a non-collinear magnetic configuration. The nonlocal magnetoresistance, defined as the voltage difference on the detection lead over the injected current, is derived analytically. The spin transfer torques on the detection lead are calculated. It is found that spin transfer torques are symmetrical for parallel and antiparallel magnetic configurations, in contrast to that in a conventional sandwiched spin valve
