Effects of current on vortex and transverse domain walls
J. He, Z. Li, S. Zhang
By using the spin torque model in ferromagnets, we compare the response of vortex and transverse walls to the electrical current. For a defect-free sample and a small applied curre…
Effects of spin current on ferromagnets
Z. Li, J. He, S. Zhang
When a spin-polarized current flows through a ferromagnet, the local magnetization receives a spin torque. Two consequences of this spin torque are studied. First, the uniformly ma…
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…
