Journal ArticleDOI
Microwave oscillations of a nanomagnet driven by a spin-polarized current
S. I. Kiselev,Jack C. Sankey,Ilya Krivorotov,N. C. Emley,Robert Schoelkopf,Robert A. Buhrman,Daniel C. Ralph +6 more
TL;DR: In this paper, the authors demonstrate a technique that allows direct electrical measurements of microwave-frequency dynamics in individual nanomagnets, propelled by a d.c. spin-polarized current.
Journal ArticleDOI
Measurement of the spin-transfer-torque vector in magnetic tunnel junctions
Jack C. Sankey,Yong-Tao Cui,Jonathan Z. Sun,John C. Slonczewski,Robert A. Buhrman,Daniel C. Ralph +5 more
TL;DR: In this article, the spin angular momentum from a spin-polarized current to a ferromagnet can generate sufficient torque to reorient the magnet's moment, which could enable the development of efficient electrically actuated magnetic memories and nanoscale microwave oscillators.
Journal ArticleDOI
Magnetic vortex oscillator driven by d.c. spin-polarized current
Vlad Pribiag,Ilya Krivorotov,Gregory D. Fuchs,Patrick M. Braganca,Ozhan Ozatay,Jack C. Sankey,Daniel C. Ralph,Robert A. Buhrman +7 more
TL;DR: In this paper, the authors demonstrate that a magnetic vortex, isolated within a nanoscale spin-valve structure, can be excited into persistent microwave-frequency oscillations by a spin-polarized d.c. current.
Journal ArticleDOI
Time-Domain Measurements of Nanomagnet Dynamics Driven by Spin-Transfer Torques
TL;DR: Time-resolved studies of magnetic relaxation allow for the direct measurement of magnetic damping in a nanomagnet and prove that this damping can be controlled electrically using spin-polarized currents.
Journal ArticleDOI
Strong and tunable nonlinear optomechanical coupling in a low-loss system
TL;DR: In this paper, the authors demonstrate that avoided crossings in the spectrum of an optical cavity containing a flexible dielectric membrane enable them to realize several different forms of the optomechanical coupling.
