Voltage-controlled spin–orbit torque switching in W/CoFeB/MgO

چکیده
Voltage control of magnetism and spintronics have been highly desirable but rarely realized. In this work, we show voltage-controlled spin–orbit torque (SOT) switching in W/CoFeB/MgO films with perpendicular magnetic anisotropy (PMA) voltage administered through SrTiO3 a high dielectric constant. We that DC can significantly lower PMA by 45%, reduce current 23%, increase the damping-like as revealed first- second-harmonic measurements. These are characteristics prerequisites for voltage-select SOT spintronic devices.

متن کاملVoltage Imbalance Compensation for Droop-Controlled Inverters in Islanded Microgrid
In this paper, a new control strategy is proposed for implementation in low-voltage microgrids with balanced/ unbalanced load circumstances. The proposed scheme contains, the power droop controllers, inner voltage and current loops, the virtual impedance loop, the voltage imbalance compensation. The proposed strategy balances the voltage of the single-phase critical loads by compensating the im...
متن کاملSwing switching of spin-torque valves
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 the critical AC spin current is significantly smaller than the corresponding DC one. The effect is understood as a consequence of the underdamped nature of the spin-torque oscillators. It allows to use the kinetic iner...

متن کاملTorque-Stiffness-Controlled Dynamic Walking
2 State of the Art Previous studies indicated that introducing adaptable compliance to dynamic walking is beneficial to modulating walking performance and extending the versatility [1-3]. However, in most of these studies, the stiffness is changed off-line. The transition of different walking patterns in real time was not investigated. Our previous study [4] has demonstrated walking pattern tra...
