Oscillation characteristics of zero-field spin transfer oscillators with field-like torque
AIP Advances, 2015 We theoretically investigate the influence of the field-like spin torque term on the oscillation characteristics of spin transfer oscillators, which are based on MgO magnetic tunnel junctions (MTJs) consisting of a perpendicular magnetized free layer and

Domain wall depinning from FM/AFM interface defects by spin-polarized current
AIP Advances, 2022 We report a theoretical investigation of the impact of spin-transfer torque on magnetic head-to-head domain walls of Fe and Ni80Fe20 (Permalloy PyTM) nanowires exchange coupled to a two-sublattice uniaxial antiferromagnetic substrate.

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

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.
