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 ...
Condensation of magnons and spinons in a frustrated ladder
(American Physical Society, 2006-06-01)
Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical analysis of a one-dimensional version of this ...
Wrinkling of a bilayer membrane
(American Physical Society, 2007-01)
The buckling of elastic bodies is a common phenomenon in the mechanics of solids. Wrinkling of membranes can often be interpreted as buckling under constraints that prohibit large-amplitude deformation. We present a ...
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 ...
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 ...
