We present a model of reversing the Neel domain walls (DWs) in the laminar domain structure of epitaxial Co(111) nanostripes. The laminar domain structure in nanostripes is induced by magnetic anisotropy, the easy axis of which is orthogonal to the long axis and lies in the plane of the stripes. Magnetization reversal in the DWs occurs by nucleation of vortices at the opposite ends of adjacent DWs and their subsequent propagation along the domain DWs. Vortices in adjacent DWs have opposite chirality. The out of plane component of the magnetization in the vortices cores is confirmed by micromagnetic modeling.
