A spin torque meter with magnetic facet domains
Nature Communications, 2018 Spin torques with different origins enable the magnetic domain wall motion, but the contributions are hard to be distinguished. Here, the authors show the method to measure both spin-magnetization transfer torque and spin–orbit torque by using mountain ...

Non-equilibrium spatial distribution of Rashba spin torque in ferromagnetic metal layer
AIP Advances, 2012 We study the spatial distribution of spin torque induced by a strong Rashba spin-orbit coupling (RSOC) in a ferromagnetic (FM) metal layer, using the Keldysh non-equilibrium Green's function method.

Spin-torque quantization and microwave sensitivity of a nano-sized spin diode
EPJ Web of Conferences, 2018 Rectification of microwave signal by the spin-torque diode is very promising for its practical applications in microwave imaging. This is due to a very high sensitivity of magnetic tunnel junction under the bias current, which was previously demonstrated

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

Nonequilibrium Spin-transfer Torque in SFNFS Junctions [PDF]
AIP Conference Proceedings, 2006 We report theoretical results for the nonequilibrium spin current and spin-transfer torque in voltage-biased SFNFS Josephson structures. The subharmonic gap structures and high voltage asymptotic behaviors of the dc and ac components of the spin current are analyzed and related to the spin-dependent inelastic scattering of quasiparticles at both F ...

Effect of spin relaxations on the spin mixing conductances for a bilayer structure
Scientific Reports, 2018 The spin current can result in a spin-transfer torque in the normal-metal(NM)—ferromagnetic-insulator(FMI) or normal-metal(NM)—ferromagnetic-metal(FMM) bilayer.

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.

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.

Spin-transfer torque generated by a topological insulator [PDF]
Nature, 2014 Magnetic devices are a leading contender for the implementation of memory and logic technologies that are non-volatile, that can scale to high density and high speed, and that do not wear out. However, widespread application of magnetic memory and logic devices will require the development of efficient mechanisms for reorienting their magnetization ...
