Optimization of spin-torque switching using AC and DC pulses
Tom Dunn, Alex Kamenev
We explore spin-torque induced magnetic reversal in magnetic tunnel junctions using combined AC and DC spin-current pulses. We calculate the optimal pulse times and current strengt…
Swing switching of spin-torque valves
Tom Dunn, Alex Kamenev
We propose a method for inducing magnetization reversal using an AC spin current polarized perpendicular to the equilibrium magnetization of the free magnetic layer. We show that t…
Dynamics of nano-magnetic oscillators
T. Dunn, A. L. Chudnovskiy, A. Kamenev
We explore how non-equilibrium noise affects spin-torque switching elements and oscillators. To do so we first discuss the deterministic dynamics of magnetic tunnel junctions, intr…
Optimization of the current pulse for spin-torque switches
Tom Dunn, Alex Kamenev
We address optimization of the spin current intensity profile needed to achieve spin torque switching of a nanomagnet. For systems with Ohmic dissipation we prove that the optimal…
Spin Torque Dynamics with Noise in Magnetic Nano-System
J. Swiebodzinski, A. Chudnovskiy, T. Dunn +1
We investigate the role of equilibrium and nonequilibrium noise in the magnetization dynamics on mono-domain ferromagnets. Starting from a microscopic model we present a detailed d…
