Nonlocal magnetization dynamics in ferromagnetic heterostructures
Two complementary effects modify the GHz magnetization dynamics of nanoscale heterostructures of ferromagnetic and normal materials relative to those of the isolated magnetic constituents. On the one…

Enhanced gilbert damping in thin ferromagnetic films.
TLDR
The precession of the magnetization of a ferromagnet is shown to transfer spins into adjacent normal metal layers, slowing down the precession corresponding to an enhanced Gilbert damping constant in the Landau-Lifshitz equation.

Current-induced torques in magnetic materials.
TLDR
How currents can generate torques that affect the magnetic orientation and the reciprocal effect in a wide variety of magnetic materials and structures is explained.

Spin pumping and magnetization dynamics in metallic multilayers
We study the magnetization dynamics in thin ferromagnetic films and small ferromagnetic particles in contact with paramagnetic conductors. A moving magnetization vector causes ‘‘pumping’’ of spins…

Spin-orbit coupling in curved graphene, fullerenes, nanotubes, and nanotube caps
A continuum model for the effective spin-orbit interaction in graphene is derived from a tight-binding model which includes the $\ensuremath{\pi}$ and $\ensuremath{\sigma}$ bands. We analyze the…

Transport properties of nonequilibrium systems under the application of light: Photoinduced quantum Hall insulators without Landau levels
In this paper, we study transport properties of non-equilibrium systems under the application of light in many-terminal measurements, using the Floquet picture. We propose and demonstrate that the…

Spin pumping and spin-transfer torques in antiferromagnets.
TLDR
By calculating how electrons scatter off a normal metal-antiferromagnetic interface, pumped spin and staggered spin currents are derived in terms of the staggered field, the magnetization, and their rates of change.

Spin battery operated by ferromagnetic resonance
Precessing ferromagnets are predicted to inject a spin current into adjacent conductors via Ohmic contacts, irrespective of a conductance mismatch with, for example, doped semiconductors. This opens…
