Controlling the Spin Torque Efficiency with Ferroelectric Barriers
A. Useinov, A. Manchon
Non-equilibrium spin-dependent transport in magnetic tunnel junctions comprising a ferroelectric barrier is theoretically investigated. The exact solutions of the free electron Sch…
Tailoring spin-orbit torque in diluted magnetic semiconductors
Hang Li, Xuhui Wang, Fatih Dogan +1
We study the spin orbit torque arising from an intrinsic linear Dresselhaus spin-orbit coupling in a single layer III-V diluted magnetic semiconductor. We investigate the transport…
Manipulating the Voltage Dependence of Tunneling Spin Torques
A. Manchon
Voltage-driven spin transfer torques in magnetic tunnel junctions provide an outstanding tool to design advanced spin-based devices for memory and reprogrammable logic applications…
Quantum spin/valley Hall effect and topological insulator phase transitions in silicene
M. Tahir, A. Manchon, K. Sabeeh +1
We present a theoretical realization of quantum spin and quantum valley Hall effects in silicene. We show that combination of an electric field and intrinsic spin-orbit interaction…
Peculiarities of Spin Polarization Inversion at a Thiophene/Cobalt Interface
Xuhui Wang, Zhiyong Zhu, Aurelien Manchon +1
We perform ab-initio calculations to investigate the spin polarization at the interface between a thiophene molecule and cobalt substrate. We find that the reduced symmetry in the…
Spin-orbit coupled transport and spin torque in a ferromagnetic heterostructure
Xuhui Wang, Christian Ortiz Pauyac, Aurelien Manchon
Ferromagnetic heterostructures provide an ideal platform to explore the nature of spin-orbit torques arising from the interplay mediated by itinerant electrons between a Rashba-typ…
