Abstract: We construct traveling wave solutions with vortex helix structures for the Schrödinger map equation

$\displaystyle \frac {\partial m}{\partial t}= m \times (\Delta m - m_3 \vec {e}_3)$$\displaystyle \quad \mbox {on} \ {\mathbb{R}}^3 \times {\mathbb{R}} $

of the form $ m(s_1,s_2, s_3 -\delta \vert\log \epsilon \vert\epsilon t)$ with traveling velocity $ \delta \vert\log \epsilon \vert\epsilon $ along the direction of the $ s_3$ axis. We use a perturbation approach which gives a complete characterization of the asymptotic behavior of the solutions.
