Localized steady-state domain wall oscillators
J. He, S. Zhang
We predict a spatially localized magnetic domain wall oscillator upon the application of an external magnetic field and a DC electric current. The amplitude and frequency of the os…
Switching speed distribution of spin-torque-induced magnetic reversal
J. He, J. Z. Sun, S. Zhang
The switching probability of a single-domain ferromagnet under spin-current excitation is evaluated using the Fokker-Planck equation(FPE). In the case of uniaxial anisotropy, the F…
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…
