Domain wall dynamics driven by adiabatic spin transfer torques
Z. Li, S. Zhang
In a first approximation, known as the adiabatic process, the direction of the spin polarization of currents is parallel to the local magnetization vector in a domain wall. Thus th…

Thermally assisted magnetization reversal in the presence of a spin-transfer torque
Z. Li, S. Zhang
We propose a generalized stochastic Landau-Lifshitz equation and its corresponding Fokker-Planck equation for the magnetization dynamics in the presence of spin transfer torques. S…

Spin diffusion at finite electric and magnetic fields
Y. Qi, S. Zhang
Spin transport properties at finite electric and magnetic fields are studied by using the generalized semiclassical Boltzmann equation. It is found that the spin diffusion equation…
