Spin Transfer Torques
D. C. Ralph, M. D. Stiles
This tutorial article introduces the physics of spin transfer torques in magnetic devices. We provide an elementary discussion of the mechanism of spin transfer torque, and review…
Time-Domain Studies of Very-Large-Angle Magnetization Dynamics Excited by Spin Transfer Torques
I. N. Krivorotov, N. C. Emley, R. A. Buhrman +1
We describe time-domain measurements which provide new information about the large-angle nonlinear dynamics of nanomagnets excited by spin-transfer torque from a spin-polarized cur…
Measurement of the Spin-Transfer-Torque Vector in Magnetic Tunnel Junctions
J. C. Sankey, Y. -T. Cui, R. A. Buhrman +3
Spin-polarized currents can transfer spin angular momentum to a ferromagnet, generating a torque that can efficiently reorient its magnetization. Achieving quantitative measurement…
Magnetic vortex oscillator driven by dc spin-polarized current
V. S. Pribiag, I. N. Krivorotov, G. D. Fuchs +5
Transfer of angular momentum from a spin-polarized current to a ferromagnet provides an efficient means to control the dynamics of nanomagnets. A peculiar consequence of this spin-…
