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…
Roles of non-equilibrium conduction electrons on magnetization dynamics of ferromagnets
S. Zhang, Z. Li
The mutual dependence of spin-dependent conduction and magnetization dynamics of ferromagnets provides the key mechanisms in various spin-dependent phenomena. We compute the respon…
Magnetization dynamics with a spin-transfer torque
Z. Li, S. Zhang
The magnetization reversal and dynamics of a spin valve pillar, whose lateral size is 6464 nm, are studied by using micromagnetic simulation in the presence of spin tra…
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…
