Dynamics of a vortex domain wall in a magnetic nanostrip: application of the collective-coordinate approach
(American Physical Society, 2008-10-01)
The motion of a vortex domain wall in a ferromagnetic strip of submicron width under the influence of an external magnetic field exhibits three distinct dynamical regimes. In a viscous regime at low fields the wall moves ...
Dynamics of domain walls in magnetic nanostrips
(American Physical Society, 2008-03-28)
We express the dynamics of domain walls in ferromagnetic nanowires in terms of collective coordinates, generalizing Thiele[psila]s steady-state results. For weak external perturbations the dynamics is dominated by a few ...
