Gate voltage modulation of spin-Hall-torque-driven magnetic switching
Luqiao Liu, Chi-Feng Pai, D. C. Ralph +1
Two promising strategies for achieving efficient control of magnetization in future magnetic memory and non-volatile spin logic devices are spin transfer torque from spin polarized…
Magnetic oscillations driven by the spin Hall effect in 3-terminal magnetic tunnel junction devices
Luqiao Liu, Chi-Feng Pai, D. C. Ralph +1
We show that direct current in a tantalum microstrip can induce steady-state magnetic oscillations in an adjacent nanomagnet through spin torque from the spin Hall effect (SHE). Th…
Spin transfer torque devices utilizing the giant spin Hall effect of tungsten
Chi-Feng Pai, Luqiao Liu, Y. Li +3
We report a giant spin Hall effect (SHE) in β-W thin films. Using spin torque induced ferromagnetic resonance with a β-W/CoFeB bilayer microstrip we determine the spin Hall angle t…
Network analyzer measurements of spin transfer torques in magnetic tunnel junctions
Lin Xue, Chen Wang, Yong-Tao Cui +3
We demonstrate a simple network-analyzer technique to make quantitative measurements of the bias dependence of spin torque in a magnetic tunnel junction. We apply a microwave curre…
Spin torque switching with the giant spin Hall effect of tantalum
Luqiao Liu, Chi-Feng Pai, Y. Li +3
We report a giant spin Hall effect (SHE) in β-Ta that generates spin currents intense enough to induce efficient spin-transfer-torque switching of ferromagnets, thereby providing a…
Resonance Measurement of Nonlocal Spin Torque in a Three-Terminal Magnetic Device
Lin Xue, Chen Wang, Yong-Tao Cui +5
A pure spin current generated within a nonlocal spin valve can exert a spin transfer torque on a nanomagnet. This nonlocal torque enables new design schemes for magnetic memory dev…
