Efficient micromagnetic modelling of spin-transfer torque and spin-orbit torque [PDF]

open access: yesAIP 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]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
Abstract 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. We highlight progress on reducing the critical currents necessary to produce spin-torque-driven magnetic switching, quantitative ...

Spin-Wave Excitation in Magnetic Insulators by Spin-Transfer Torque [PDF]

open access: yesPhysical Review Letters, 2012
We study the excitation of spin waves in magnetic insulators by the current-induced spin-transfer torque. We predict preferential excitation of surface spin waves induced by an easy-axis surface anisotropy with critical current inversely proportional to the penetration depth and surface anisotropy. The surface modes strongly reduce the critical current

PARAMETER SPACE FOR THERMAL SPIN-TRANSFER TORQUE [PDF]

open access: yesSPIN, 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 across an ultra thin MgO barrier.

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

open access: yes, 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).

Comparison of the spin-transfer torque mechanisms in a three-terminal spin-torque oscillator. [PDF]

open access: yesJ Appl Phys, 2018
We have studied magnetization dynamics in three-terminal spin-torque oscillators (STOs) and present a direct method to compare the efficiencies of exciting oscillations in STOs through two mechanisms of spin transfer torque: the spin filtering torque (SFT) and the spin-orbit torque (SOT).

Spin Pumping and Spin-Transfer Torques in Antiferromagnets [PDF]

open access: yesPhysical 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 ...

Evidence for Thermal Spin-Transfer Torque [PDF]

open access: yesPhysical 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 ...
