Foros, J. (author), Brataas, A. (author), Tserkovnyak, Y. (author), Bauer, G.E.W. (author)In the presence of spatial variation in the magnetization direction, electric current noise causes a fluctuating spin-transfer torque that increases the fluctuations of the ferromagnetic order parameter. By the fluctuationdissipation theorem, the fluctuations at thermal equilibrium are related to the viscous magnetization damping, which in...journal article 2008

Foros, J. (author), Brataas, A. (author), Bauer, G.E.W. (author), Tserkovnyak, Y. (author)The interplay between current and magnetization fluctuations and dissipation in layered-ferromagnetic-normal-metal nanostructures is investigated. We use scattering theory and magnetoelectronic circuit theory to calculate charge and spin-current fluctuations. Via the spin-transfer torque, spin-current noise causes a significant enhancement of...journal article 2009
