Abstract: High-purity magnetic CoNi submicrospherical chains, each of length 20 μm - 30 μm and self-assembled from fcc-phase CoNi submicrospheres of average diameter 800 nm, are synthesized via a surfactant-assisted solvothermal route without the aid of nucleation agent. The effects of surfactant and reducing agent on the morphology and size of the CoNi chains are studied, and a possible growth mechanism for the CoNi chains is proposed. The CoNi chains show ferromagnetic characteristics with a similarly small saturation magneti-zation of 104.1 emu/g and a larger coercivity of 150 Oe at room temperature compared to the monodispersed CoNi submicrospheres of 105 emu/g and 34 Oe as a result of the increased shape
