Spin-orbit torque engineering via oxygen manipulation
Xuepeng Qiu, Kulothungasagaran Narayanapillai, Yang Wu +7
Spin transfer torques allow the electrical manipulation of the magnetization at room temperature, which is desirable in spintronic devices such as spin transfer torque memories. Wh…
Extremely large magnetoresistance in few-layer graphene/boron-nitride heterostructures
Kalon Gopinadhan, Young Jun Shin, Rashid Jalil +4
Understanding magnetoresistance, the change in electrical resistance upon an external magnetic field, at the atomic level is of great interest both fundamentally and technologicall…
Extrinsic Spin Hall Effect from Anisotropic Rashba Spin-Orbit Coupling in Graphene
H-Y. Yang, Chunli Huang, Hector Ochoa +1
We study the effect of anisotropy of the Rashba coupling on the extrinsic spin Hall effect due to spin-orbit active adatoms on graphene. In addition to the intrinsic spin-orbit cou…
Graphene terahertz modulators by ionic liquid gating
Yang Wu, Chan La-o-vorakiat, Xuepeng Qiu +7
Graphene based THz modulators are promising due to the conical band structure and high carrier mobility of graphene. Here, we tune the Fermi level of graphene via electrical gating…
Magnetization reversal using excitation of collective modes in nanodot matrices
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
The large arrays of magnetic dots are the building blocks of magnonic crystals and the emerging bit patterned media for future recording technology. In order to fully utilize the f…
Synchronization of spin-transfer torque oscillators by spin pumping, inverse spin Hall, and spin Hall effects
Mehrdad Elyasi, Charanjit S. Bhatia, Hyunsoo Yang
We have proposed a method to synchronize multiple spin-transfer torque oscillators based on spin pumping, inverse spin Hall, and spin Hall effects. The proposed oscillator system c…
