Asymmetric domain nucleation and unusual magnetization reversal in ultrathin Co films with perpendicular anisotropy
(American Physical Society, 2007-03-16)
We report unexpected phenomena during magnetization reversal in ultrathin Co films and Co/Pt multilayers with perpendicular anisotropy. Using magneto-optical Kerr microscopy and magnetic force microscopy we have observed ...
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 ...
Stripes in thin ferromagnetic films with out-of-plane anisotropy
(American Physical Society, 2007-05-01)
We examine the T=0 phase diagram of a thin ferromagnetic film with a strong out-of-plane anisotropy (e.g., Co/Pt multilayers) in the vicinity of the reorientation phase transition. The phase diagram in the anisotropy-applied-field ...
