The effect of geometrical confinement and chirality on domain wall pinning behavior in planar nanowires

Chirality-dependent domain wall pinning in a multinotched planar nanowire and chirality preservation using transverse magnetic fields

Effective pinning energy landscape perturbations for propagating magnetic domain walls

The interaction between a magnetic domain wall and a pinning site is explored in a planar nanowire using micromagnetics to reveal perturbations of the pinning energetics for propagating domain walls. Numerical simulations in the high damping 'quasi-static' and low damping 'dynamic' regimes are compared and show clear differences in de-pinning fields, indicating that dynamical micromagnetic mode...

Controlling domain wall pinning in planar nanowires by selecting domain wall type and its application in a memory concept

Tunable remote pinning of domain walls in magnetic nanowires.

Domain wall (DW) pinning in ferromagnetic nanowires is in general a complex process. Distortions of the DW shape make quantitative agreement between modeling and experiment difficult. Here we demonstrate pinning using nanometer scale localized stray fields. This type of interaction gives well-characterized, tailorable potential landscapes that do not appreciably distort the DW. Our experimental...
