Fig. 3 — a Top view of the calculated spin structure in the Co₅–Fe₂₀–Co₅ chain. Blue and red spheres correspond to Co and Fe atoms, respectively. The length of the arrows is proportional to the size of the in-plane component of the magnetic moment at each particular site. b x, y, and z components of the magnetic moments in the Co₅–Fe₂₀–Co₅-, the Fe₂₀–Co₅-, and the Fe₂₀ chains. c Side view of the Co₅–Fe₂₀–Co₅ chain cycloidal spin spiral along the negative x direction. d Total magnetic moment of the atoms along all three chains.
