Electric and thermal spin transfer torques across ferromagnetic/normal/ferromagnetic graphene junctions

open access: yesNew Journal of Physics, 2020
We investigate the spin transfer torque (STT) driven by electric bias voltages across and temperature gradients through ferromagnetic/normal/ferromagnetic graphene junctions.

Theory of spin accumulation and spin transfer torque in a magnetic domain wall [PDF]

open access: yes, 2009
We study spin accumulation and spin transfer torque in a domain wall by solving the Boltzmann equation with a diffusion approximation. We obtained the analytical expressions of spin accumulation and spin transfer torque.

Spin transfer torques

open access: yesJournal of Magnetism and Magnetic Materials, 2008
This tutorial article introduces the physics of spin transfer torques in magnetic devices. We provide an elementary discussion of the mechanism of spin transfer torque, and review the theoretical and experimental progress in this field. Our intention is to be accessible to beginning graduate students.

Subterahertz ferrimagnetic spin-transfer torque oscillator [PDF]

open access: yesPhysical Review B, 2019
A theory of magnetization dynamics in ferrimagnetic materials with antiparallel aligned spin sub-lattices under action of spin-transfer torques (STT) is developed. We consider magnetization dynamics in GdFeCo layers in two cases of magnetic anisotropy: easy plane and easy axis.

Anatomy of spin-transfer torque

open access: yesPhysical Review B, 2002
Spin-transfer torques occur in magnetic heterostructures because the transverse component of a spin current that flows from a non-magnet into a ferromagnet is absorbed at the interface. We demonstrate this fact explicitly using free electron models and first principles electronic structure calculations for real material interfaces.

Spin current pumped by confined breathing skyrmion

open access: yesNew Journal of Physics, 2020
Spin pumping is a widely recognized method to generate the spin current in the spintronics, which can be found in varieties of magnetic materials and is acknowledged as a fundamentally dynamic process equivalent to the spin-transfer torque. In this work,

Spin-transfer torque induced reversal in magnetic domains [PDF]

open access: yes, 2008
Using the complex stereographic variable representation for the macrospin, from a study of the nonlinear dynamics underlying the generalized Landau-Lifshitz(LL) equation with Gilbert damping, we show that the spin-transfer torque is effectively ...
