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 ...

Alternating current-induced interfacial spin-transfer torque [PDF]
Physical Review B, 2019 We investigate an interfacial spin-transfer torque and $ $-term torque with alternating current (AC) parallel to a magnetic interface. We find that both torques are resonantly enhanced as the AC frequency approaches to the exchange splitting energy.

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

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-transfer torque for continuously variable magnetization [PDF]
Physical Review B, 2006 We report quantum and semi-classical calculations of spin current and spin-transfer torque in a free-electron Stoner model for systems where the magnetization varies continuously in one dimension.Analytic results are obtained for an infinite spin spiral and numerical results are obtained for realistic domain wall profiles. The adiabatic limit describes

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

AIP Advances, 2023 In this study, the validity of our DFT-based self-developed JunPy+SOT calculation method has been rigorously confirmed by the perpendicular magnetic anisotropy (PMA) induced effective magnetic anisotropy field of 5.6 kOe in a 1.5 nm-thick iron thin film.

Spin Pumping and Spin-Transfer Torques in Antiferromagnets [PDF]
Physical Review Letters, 2014 Spin pumping and spin-transfer torques are two reciprocal phenomena widely studied in ferromagnetic materials. However, pumping from antiferromagnets and its relation to current-induced torques have not been explored. By calculating how electrons scatter off a normal metal-antiferromagnetic interface, we derive pumped spin and staggered spin currents ...

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.
