Efficient micromagnetic modelling of spin-transfer torque and spin-orbit torque

AIP Advances, 2018
While the spin-diffusion model is considered one of the most complete and accurate tools for the description of spin transport and spin torque, its solution in the context of dynamical micromagnetic simulations is numerically expensive.

Spin-transfer torque in nanoscale magnetic devices [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
We discuss recent highlights from research at Cornell University, Ithaca, New York, regarding the use of spin-transfer torques to control magnetic moments in nanoscale ferromagnetic devices.

PARAMETER SPACE FOR THERMAL SPIN-TRANSFER TORQUE [PDF]

SPIN, 2013
Thermal spin-transfer torque describes the manipulation of the magnetization by the application of a heat flow. The effect has been calculated theoretically by Jia et al. in 2011. It is found to require large temperature gradients in the order of Kelvins

Subterahertz ferrimagnetic spin-transfer torque oscillator [PDF]

Physical Review B, 2019
A theory of magnetization dynamics in ferrimagnetic materials with antiparallel aligned spin sublattices under the action of spin-transfer torques (STTs) is developed. In contrast with antiferromagnets, the magnetic sublattices in ferrimagnets are formed

Spin-transfer-torque-induced phenomena

Journal of Physics D: Applied Physics, 2011
This cluster, consisting of five invited articles on spin-transfer torque, offers the very first review covering both magnetization reversal and domain-wall displacement induced by a spin-polarized current.

MODELS OF SPIN TORQUE USING SELF-CONSISTENT SOLUTIONS OF THE MAGNETISATION AND SPIN ACCUMULATION [PDF]

, 2013
A model of spin accumulation (m) is proposed to develop theoretical approaches to calculate the m in any arbitrary magnetic structure. The model is based on generalising the approach of Zhang, Levy and Fert (PRL 88, 236601, 2002).

Evidence for Thermal Spin-Transfer Torque [PDF]

Physical Review Letters, 2010
Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both the switching field and the magnitude of the voltage response are found to be dependent on the heat ...

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 ...
