Creep of current-driven domain-wall lines: intrinsic versus extrinsic pinning
R. A. Duine, C. Morais Smith
We present a model for current-driven motion of a magnetic domain-wall line, in which the dynamics of the domain wall is equivalent to that of an overdamped vortex line in an aniso…
Current-Induced Torques in Magnetic Metals: Beyond Spin Transfer
P. M. Haney, R. A. Duine, A. S. Nunez +1
Current-induced torques on ferromagnetic nanoparticles and on domain walls in ferromagnetic nanowires are normally understood in terms of transfer of conserved spin angular momentu…
Spin pumping by a field-driven domain wall
R. A. Duine
We calculate the charge current in a metallic ferromagnet to first order in the time derivative of the magnetization direction. Irrespective of the microscopic details, the result…
Effective temperature and Gilbert damping of a current-driven localized spin
A. S. Nunez, R. A. Duine
Starting from a model that consists of a semiclassical spin coupled to two leads we present a microscopic derivation of the Langevin equation for the direction of the spin. For slo…
Quantum Hall ferromagnetism in graphene: a SU(4) bosonization approach
R. L. Doretto, C. Morais Smith
We study the quantum Hall effect in graphene at filling factors ν= 0 and ν= \pm, concentrating on the quantum Hall ferromagnetic regime, within a non-perturbative bosonization form…
Functional Keldysh Theory of Spin Torques
R. A. Duine, A. S. Nunez, Jairo Sinova +1
We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find…
