Spin-transfer torque and current-induced vortex superlattices in nanomagnets
Influence of the spin-transfer torque on the vortex state magnetic nanodisk is studied numerically via the Slonczewski-Berger mechanism. The existence of a critical current is determined for the case of same-directed electrical current, its spin polarization, and the polarity of the vortex. The critical current separates two regimes: (i) deformed but static vortex state and (ii) essentially dyn...
متن کاملInterfacial DMI Induced Directional Spin Wave in Spin-torque Oscillators
Spin torque oscillators (STOs) are currently of great interest due to its wide tunable frequencies, low energy consumption and high quality factors compared with traditional oscillators. Here, we report the characteristics of the nanocontact-(NC-)STO in the presence of interfacial Dzyaloshinskii-Moriya interaction (DMI), using micromagnetic simulations. We find that the DMI can decrease the STO...
متن کاملShot noise of spin current and spin transfer torque.
We report the theoretical investigation of the shot noise of the spin current (S(σ)) and the spin transfer torque (S(τ)) for non-collinear spin polarized transport in a spin-valve device which consists of a normal scattering region connected by two ferromagnetic electrodes (MNM system). Our theory was developed using the non-equilibrium Green's function method, and general nonlinear S(σ) - V an...
متن کاملSpin Hall Current and Spin-transfer Torque in Ferromagnetic Metal
We theoretically examine the spin-transfer torque in the presence of spin-orbit interaction (SOI) at impurities in a ferromagnetic metal on the basis of linear response theory. We obtained, in addition to the usual spin-transfer torque, a new contributioin ∼ jSH ·∇n in the first order in SOI, where jSH is the spin Hall current driven by an external electric field. This is a reaction to inverse ...
متن کاملReflection mechanism for generating spin transfer torque without charge current
A reflection mechanism for generating spin-transfer torque is proposed. It is due to interference of bias-driven nonequilibrium electrons incident on a switching junction, with the electrons reflected from an insulating barrier inserted in the junction after the switching magnet. It is shown, using the rigorous Keldysh formalism, that this out-of-plane torque T? is proportional to an applied bi...
