Spin‐Torque Memristors Based on Perpendicular Magnetic Tunnel Junctions for Neuromorphic Computing
Advanced Science, 2021 Spin‐torque memristors are proposed in 2009, and can provide fast, low‐power, and infinite memristive behavior for neuromorphic computing and large‐density non‐volatile memory.

Domain-wall motion induced by spin transfer torque delivered by helicity-dependent femtosecond laser [PDF]
, 2019 In magnetic wires with perpendicular anisotropy, moving domain with only current or only circularly polarized light requires a high power. Here, we propose to reduce it by using both short current pulses and femtosecond laser pulses simultaneously.

Spin torque on the surface of graphene in the presence of spin orbit splitting
AIP Advances, 2013 We study theoretically the spin transfer torque of a ferromagnetic layer coupled to (deposited onto) a graphene surface in the presence of the Rashba spin orbit coupling (RSOC). We show that the RSOC induces an effective magnetic field, which will result

Spin-transfer torque induced spin waves in antiferromagnetic insulators
New Journal of Physics, 2015 We explore the possibility of exciting spin waves in insulating antiferromagnetic films by injecting spin current at the surface. We analyze both magnetically compensated and uncompensated interfaces.

Magnetic domain wall motion in a nanowire: depinning and creep
, 2011 The domain wall motion in a magnetic nanowire is examined theoretically in the regime where the domain wall driving force is weak and its competition against disorders is assisted by thermal agitations.

Spin-Torque Generation in Topological-Insulator-Based Heterostructures [PDF]
, 2016 Heterostructures utilizing topological insulators exhibit a remarkable spin-torque efficiency. However, the exact origin of the strong torque, in particular whether it stems from the spin-momentum locking of the topological surface states or rather from ...
