Spin-Torque Switching with the Giant Spin Hall Effect of Tantalum
Giant Spin Hall One of the primary challenges in the field of spin-electronics, which exploits the electron's spin rather than its charge, is to create strong currents of electrons with polarizedExpand
Spin-torque ferromagnetic resonance induced by the spin Hall effect.
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 current through aExpand
Spintronics: A Spin-Based Electronics Vision for the Future
This review describes a new paradigm of electronics based on the spin degree of freedom of the electron. Either adding the spin degree of freedom to conventional charge-based electronic devices orExpand
Current-induced switching of perpendicularly magnetized magnetic layers using spin torque from the spin Hall effect.
We show that in a perpendicularly magnetized Pt/Co bilayer the spin-Hall effect (SHE) in Pt can produce a spin torque strong enough to efficiently rotate and switch the Co magnetization. We calculateExpand
Microwave oscillations of a nanomagnet driven by a spin-polarized current
The recent discovery that a spin-polarized electrical current can apply a large torque to a ferromagnet, through direct transfer of spin angular momentum, offers the possibility of manipulatingExpand
Spin transfer torque devices utilizing the giant spin Hall effect of tungsten
We report a giant spin Hall effect in β-W thin films. Using spin torque induced ferromagnetic resonance with a β-W/CoFeB bilayer microstrip, we determine the spin Hall angle to be |θSHβ-W|=0.30±0.02,Expand
Measurement of the spin-transfer-torque vector in magnetic tunnel junctions
The transfer of spin angular momentum from a spin-polarized current to a ferromagnet can generate sufficient torque to reorient the magnet’s moment. This torque could enable the development ofExpand
Spin-transfer-driven ferromagnetic resonance of individual nanomagnets.
We demonstrate a technique that enables ferromagnetic resonance measurements of the normal modes for magnetic excitations in individual nanoscale ferromagnets, smaller in volume by more than a factorExpand
Ultrafine metal particles
In this paper we present a novel and versatile technique for the production of ultrafine metal particles by evaporation from a temperature‐regulated oven containing a reduced atmosphere of an inertExpand
Magnetic vortex oscillator driven by d.c. spin-polarized current
Transfer of angular momentum from a spin-polarized current to a ferromagnet provides an efficient means to control the magnetization dynamics of nanomagnets. A peculiar consequence of this spinExpand
