Switching of perpendicular magnetization by spin-orbit torques in the absence of external magnetic fields
Guoqiang Yu, Pramey Upadhyaya, Yabin Fan +10
Magnetization switching by current-induced spin-orbit torques (SOTs) is of great interest due to its potential applications for ultralow-power memory and logic devices. In order to…
Electric-field induced domain-wall dynamics: depinning and chirality switching
Pramey Upadhyaya, Ritika Dusad, Silas Hoffman +4
We theoretically study the equilibrium and dynamic properties of nanoscale magnetic tunnel junctions (MTJs) and magnetic wires, in which an electric field controls the magnetic ani…
Ultralow-current-density and bias-field-free spin-transfer nano-oscillator
Zhongming Zeng, Giovanni Finocchio, Baoshun Zhang +8
The spin-transfer nano-oscillator (STNO) offers the possibility of using the transfer of spin angular momentum via spin-polarized currents to generate microwave signals. However, a…
