Abstract

We have investigated magnetic domain wall propagation behavior in wavy nanowires using micromagnetic simulation. The wire width is set to have sinusoidal distortion with variation of spatial frequency and phase. We have analyzed domain wall speed under a constant external field with variation of wavy geometry. Interestingly, with introduction of proper wavy geometry, domain wall speed becomes faster than the speed of domain wall in a straight wire, where a periodic change of domain wall inner structure has been observed with suppression of vortex structure formation.
