Charge pumping and the colored thermal voltage noise in spin valves
Jiang Xiao, Gerrit E. W. Bauer, Sadamichi Maekawa +1
Spin pumping by a moving magnetization gives rise to an electric voltage over a spin valve. Thermal fluctuations of the magnetization manifest themselves as increased thermal volta…
Spin-transfer torque in magnetic tunnel junctions: Scattering theory
Jiang Xiao, Gerrit E. W. Bauer, Arne Brataas
We study the bias-dependent spin-transfer torque in magnetic tunnel junctions in the Stoner model by scattering theory. We show that the in-plane (Slonczewski type) torque vanishes…
Charge pumping in magnetic tunnel junctions: Scattering theory
Jiang Xiao, Gerrit E. W. Bauer, Arne Brataas
We study theoretically the charge transport pumped by magnetization dynamics through epitaxial FIF and FNIF magnetic tunnel junctions (F: Ferromagnet, I: Insulator, N: Normal metal…
Spin Transfer Torque for Continuously Variable Magnetization
Jiang Xiao, A. Zangwill, M. D. Stiles
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 i…
Macrospin Models of Spin Transfer Dynamics
Jiang Xiao, A. Zangwill, M. D. Stiles
The current-induced magnetization dynamics of a spin valve are studied using a macrospin (single domain) approximation and numerical solutions of a generalized Landau-Lifshitz-Gilb…
Boltzmann Test of Slonczewski's Theory of Spin Transfer Torque
Jiang Xiao, A. Zangwill, M. D. Stiles
We use a matrix Boltzmann equation formalism to test the accuracy of Slonczewski's theory of spin-transfer torque in thin-film heterostructures where a non-magnetic spacer layer se…
