Spin Torque Ferromagnetic Resonance Induced by the Spin Hall Effect
Luqiao Liu, Takahiro Moriyama, D. C. Ralph +1
We demonstrate that the spin Hall effect in a thin film with strong spin-orbit scattering can excite magnetic precession in an adjacent ferromagnetic film. The flow of alternating…
Time-resolved detection of spin-transfer-driven ferromagnetic resonance and spin torque measurement in magnetic tunnel junctions
Chen Wang, Yong-Tao Cui, Jordan A. Katine +2
Several experimental techniques have been introduced in recent years in attempts to measure spin transfer torque in magnetic tunnel junctions (MTJs). The dependence of spin torque…
Spin-torque driven magnetic vortex self-oscillations in perpendicular magnetic fields
G. Finocchio, V. S. Pribiag, L. Torres +2
We have employed complete micromagnetic simulations to analyze dc current driven self-oscillations of a vortex core in a spin-valve nanopillar in a perpendicular field by including…
